Generalized multifractality in two-dimensional disordered systems of chiral symmetry classes

Jonas F. Karcher, Ilya A. Gruzberg, and Alexander D. Mirlin

Phys. Rev. B 107, 104202 (2023) - Published 22 March, 2023

Anderson transitions between metals and insulators exhibit fascinating spatial structure, fluctuations, and correlations of electronic wave functions. This structure has been properly characterized by the authors in terms of multifractals with continuous spectra of scaling exponents. In this paper, the authors focus on Anderson transitions in systems with a sublattice (chiral) symmetry. This particular class of Anderson transitions has not been well-studied in the past, and the authors fill this gap with a thorough analytical and numerical study of multifractal spectra in the metallic phase and at the critical point of the Anderson transition.

Robert Oliva, Esther Ritov, Faris Horani, Iñigo Etxebarria, Adam K. Budniak, Yaron Amouyal, Efrat Lifshitz, and Mael Guennou

Phys. Rev. B 107, 104415 (2023) - Published 16 March, 2023

Antiferromagnetic MnPS3 and diamagnetic ZnPS3 belong to a family of two-dimensional compounds that exhibit a rich variety of magnetic ordering. Low-temperature Raman spectroscopy and SQUID magnetometer measurements are performed on both compounds and their alloy in order to evaluate a possible Jahn-Teller distortion as well as to reveal magnetic and alloy signatures. With the aid of first-principles calculations, a description of the lattice dynamics of the system is presented, together with the magnetic phase diagram across the entire compositional range.

Quantum oscillations in the centrosymmetric skyrmion-hosting magnet GdRu2Si2

N. Matsuyama, T. Nomura, S. Imajo, T. Nomoto, R. Arita, K. Sudo, M. Kimata, N. D. Khanh, R. Takagi, Y. Tokura, S. Seki, K. Kindo, and Y. Kohama

Phys. Rev. B 107, 104421 (2023) - Published 21 March, 2023

The skyrmion formation mechanism in centrosymmetric systems remains to be understood, partially because of the lack of fundamental understanding of the electronic structure. The authors observe de Haas–van Alphen and Shubnikov–de Haas oscillations in high magnetic fields up to 58 T on GdRu2Si2, which is one of such centrosymmetric skyrmion-hosting magnets with the shortest skyrmion diameter ever found. Combined with first-principles calculations, the authors now reveal the electronic structure of GdRu2Si2 and its reconstruction at the magnetic phase boundary.

First-principles theory of the pressure-induced invar effect in FeNi alloys

Amanda Ehn, Björn Alling, and Igor A. Abrikosov

Phys. Rev. B 107, 104422 (2023) - Published 21 March, 2023

Beside the classic Fe64Ni36 Invar alloy, which shows an anomalously low thermal expansion at ambient pressure, Fe-Ni alloys with a higher nickel composition can be driven to Invar behavior by pressure. The authors investigate the pressure induced Invar effect theoretically and demonstrate that it can be explained by a magnetic transition from a ferromagnetic state at high volume to a complex noncollinear state upon compression. They relate the Invar effect to the increasing contribution of magnetic entropy with pressure.

Spin-orbital order and excitons in magnetoresistive HoBi

Phys. Rev. B 107, 104423 (2023) - Published 22 March, 2023

The rare-earth monopnictides RX have been found to exhibit exotic topological three-dimensional states, coupled to unique magnetotransport responses such as extreme magnetoresistance. These findings generated interest to understand the interplay between electronic band topology, transport, and magnetism in RX. While neutron scattering is indispensable to fully characterize magnetism, there is very little modern work on this family of compounds. Since the details of the magnetism have a profound impact on the electronic band topology and transport in materials, the authors present here a thorough characterization of the magnetism in HoBi, based on modern neutron scattering techniques.

Unraveling the role of Sm 4f electrons in the magnetism of SmFeO3

Danila Amoroso, Bertrand Dupé, and Matthieu J. Verstraete

Phys. Rev. B 107, 104427 (2023) - Published 28 March, 2023

Magnetic rare-earth orthoferrite perovskites (RFeO3) host a variety of functional properties particularly suitable for next-generation, ultrafast spintronic devices. A key ingredient is the complex magnetic interaction at play between the two magnetic substructures. SmFeO3 has attracted particular interest because of its high-temperature spin reorientation transition and anomalous temperature-dependent lattice vibrational modes. Through first-principles calculations, the authors unveil here the interplay of the Sm-Fe exchange with the strong Sm f anisotropy as the dominant microscopic mechanism, and the nature of the anomalous vibrations.

Multilayer graphenes as a platform for interaction-driven physics and topological superconductivity

Areg Ghazaryan, Tobias Holder, Erez Berg, and Maksym Serbyn

Phys. Rev. B 107, 104502 (2023) - Published 2 March, 2023

Multilayer graphene systems without a moiré superlattice have emerged as an alternative platform to study interaction and superconducting phases. This study systematically compares density of states of multilayer graphene with different stacking. It identifies tetralayer graphene with rhombohedral (ABCA) stacking as the most promising material for realization of broken-symmetry phases. In-depth analysis of the phase diagram of ABCA graphene shows that, for the accessible range of experimental parameters, the material supports corrugated Fermi surface, which can realize a topological p+ip superconducting state with chiral Majorana edge modes.

Superconducting properties and gap structure of the topological superconductor candidate Ti3Sb

R. Chapai, M. P. Smylie, H. Hebbeker, D. Y. Chung, W.-K. Kwok, J. F. Mitchell, and U. Welp

Phys. Rev. B 107, 104504 (2023) - Published 2 March, 2023

A15 materials have been studied extensively due to the importance of Nb3Sn for the fabrication of high-field superconducting magnets. Recently, their topological properties have generated substantial interest as these materials have potential to exhibit exotic phenomena, such as topological superconductivity and large spin Hall effect. Here, the authors employ various complementary bulk measurement techniques to characterize the superconducting properties of the A15 material Ti3Sb. They report modestly strong superconducting coupling, indications for paramagnetic limiting, and a full superconducting gap.

Optimizing the transport of Majorana zero modes in one-dimensional topological superconductors

Bill P. Truong, Kartiek Agarwal, and T. Pereg-Barnea

Phys. Rev. B 107, 104516 (2023) - Published 24 March, 2023

It is well known that Majorana zero modes can be harnessed for applications in topological quantum computation. Transitions away from the ground-state subspace, where computations are performed, are detrimental. The authors study the diabatic error which quantifies these transitions as Majorana zero modes are transported across a superconducting wire. Using the ‘piano key’ approach for transport, the authors find that there exists an optimal number of keys which reduces the diabatic error.

Minimal one-dimensional model of bad metal behavior from fast particle-hole scattering

Yan-Qi Wang, Roman Rausch, Christoph Karrasch, and Joel E. Moore

Phys. Rev. B 107, L100301 (2023) - Published 10 March, 2023

The authors propose here a mechanism and an explicit one-dimensional model to realize the linear-in-temperature resistivity that is the hallmark of bad metals. They then verify the behavior with advanced DMRG-type simulations. These results open a new approach to understanding the limits of relaxation generated by local interactions in extended many-body systems. This work should push forward research into understanding some of the most basic questions about transport for 1D and critical systems, which bridge quantum matter and quantum chaos.

FeRhCrSi: Spin semimetal with spin-valve behavior at room temperature

Y. Venkateswara, Jadupati Nag, S. Shanmukharao Samatham, Akhilesh Kumar Patel, P. D. Babu, Manoj Raama Varma, Jayita Nayak, K. G. Suresh, and Aftab Alam

Phys. Rev. B 107, L100401 (2023) - Published 2 March, 2023

FeRhCrSi shows unconventional magnetic and transport properties. It belongs to one of the rare spintronic material classes, namely, spin semimetals. Transport measurements reveal its semimetallic nature, which is further confirmed by ab initio calculations on the partially disordered L21 structure, experimentally synthesized by the authors. The most striking feature is theasymmetric magnetoresistance variation with field at room temperature, clearly revealing spin-valve behavior. Disorder-induced ferrimagnetic regions within the ferromagnetic host are proposed to be the reason for this behavior. Simultaneous observation of spin semimetallic and spin valve features makes this alloy quite interesting both from fundamental and applied perspectives.

Strong lateral exchange coupling and current-induced switching in single-layer ferrimagnetic films with patterned compensation temperature

Zhentao Liu, Zhaochu Luo, Ivan Shorubalko, Christof Vockenhuber, Laura J. Heyderman, Pietro Gambardella, and Aleš Hrabec

Phys. Rev. B 107, L100412 (2023) - Published 20 March, 2023

Interlayer couplings are widely used in spintronic devices based on magnetic multilayers. Here, the authors demonstrate instead a strong tunable coupling between adjacent regions of a single ferrimagnetic layer, based on the exchange interaction. They unveil a large lateral exchange bias by spatially patterning the compensation temperature of the ferrimagnet. Furthermore, they show electrical switching of ferrimagnetic domains utilizing the lateral exchange coupling mechanism in combination with spin-orbit torques.

Antiferromagnetic MnPS3 and diamagnetic ZnPS3 belong to a family of two-dimensional compounds that exhibit a rich variety of magnetic ordering. Low-temperature Raman spectroscopy and SQUID magnetometer measurements are performed on both compounds and their alloy in order to evaluate a possible Jahn-Teller distortion as well as to reveal magnetic and alloy signatures. With the aid of first-principles calculations, a description of the lattice dynamics of the system is presented, together with the magnetic phase diagram across the entire compositional range.

The skyrmion formation mechanism in centrosymmetric systems remains to be understood, partially because of the lack of fundamental understanding of the electronic structure. The authors observe de Haas–van Alphen and Shubnikov–de Haas oscillations in high magnetic fields up to 58 T on GdRu2Si2, which is one of such centrosymmetric skyrmion-hosting magnets with the shortest skyrmion diameter ever found. Combined with first-principles calculations, the authors now reveal the electronic structure of GdRu2Si2 and its reconstruction at the magnetic phase boundary.

First-principles theory of the pressure-induced invar effect in FeNi alloys

Phys. Rev. B 107, 104422 (2023) - Published 21 March, 2023

Beside the classic Fe64Ni36 Invar alloy, which shows an anomalously low thermal expansion at ambient pressure, Fe-Ni alloys with a higher nickel composition can be driven to Invar behavior by pressure. The authors investigate the pressure induced Invar effect theoretically and demonstrate that it can be explained by a magnetic transition from a ferromagnetic state at high volume to a complex noncollinear state upon compression. They relate the Invar effect to the increasing contribution of magnetic entropy with pressure.

The rare-earth monopnictides RX have been found to exhibit exotic topological three-dimensional states, coupled to unique magnetotransport responses such as extreme magnetoresistance. These findings generated interest to understand the interplay between electronic band topology, transport, and magnetism in RX. While neutron scattering is indispensable to fully characterize magnetism, there is very little modern work on this family of compounds. Since the details of the magnetism have a profound impact on the electronic band topology and transport in materials, the authors present here a thorough characterization of the magnetism in HoBi, based on modern neutron scattering techniques.

Magnetic rare-earth orthoferrite perovskites (RFeO3) host a variety of functional properties particularly suitable for next-generation, ultrafast spintronic devices. A key ingredient is the complex magnetic interaction at play between the two magnetic substructures. SmFeO3 has attracted particular interest because of its high-temperature spin reorientation transition and anomalous temperature-dependent lattice vibrational modes. Through first-principles calculations, the authors unveil here the interplay of the Sm-Fe exchange with the strong Sm f anisotropy as the dominant microscopic mechanism, and the nature of the anomalous vibrations.

Multilayer graphene systems without a moiré superlattice have emerged as an alternative platform to study interaction and superconducting phases. This study systematically compares density of states of multilayer graphene with different stacking. It identifies tetralayer graphene with rhombohedral (ABCA) stacking as the most promising material for realization of broken-symmetry phases. In-depth analysis of the phase diagram of ABCA graphene shows that, for the accessible range of experimental parameters, the material supports corrugated Fermi surface, which can realize a topological p+ip superconducting state with chiral Majorana edge modes.

A15 materials have been studied extensively due to the importance of Nb3Sn for the fabrication of high-field superconducting magnets. Recently, their topological properties have generated substantial interest as these materials have potential to exhibit exotic phenomena, such as topological superconductivity and large spin Hall effect. Here, the authors employ various complementary bulk measurement techniques to characterize the superconducting properties of the A15 material Ti3Sb. They report modestly strong superconducting coupling, indications for paramagnetic limiting, and a full superconducting gap.

It is well known that Majorana zero modes can be harnessed for applications in topological quantum computation. Transitions away from the ground-state subspace, where computations are performed, are detrimental. The authors study the diabatic error which quantifies these transitions as Majorana zero modes are transported across a superconducting wire. Using the ‘piano key’ approach for transport, the authors find that there exists an optimal number of keys which reduces the diabatic error.
