Synthesis of osmium hydride under high hydrogen pressure

Mikhail A. Kuzovnikov, Vasily S. Minkov, Stella Chariton, Vitali B. Prakapenka, and Mikhail I. Eremets

Phys. Rev. B 102, 214109 (2020) - Published 15 December, 2020

High pressure is a very effective tool for the synthesis of new hydrogen-rich compounds, because it dramatically increases the reactivity of molecular hydrogen. Various new hydrides have been discovered in recent years, including superhydrides and materials with nearly room-temperature superconductivity (H3S, LaH10, YH9, etc.). Here, the authors study the hydrogen reactivity with osmium, which was the last group IV-X transition metal that could not be hydrogenated until now.

Precise control of Jeff=12 magnetic properties in Sr2IrO4 epitaxial thin films by variation of strain and thin film thickness

The 5d transition metal oxides offer a plethora of possibilities to further enrich the fascinating physics of complex 3d compounds by generating novel physical properties at the strong spin-orbit coupling limit. Here, the authors demonstrate that the magnetic correlation length in Sr2IrO4 thin films strongly depends on the film thickness, while it is completely independent of their strain state. This creates the opportunity to fine-tune the magnetic correlation length and may open up important inroads into the stabilization of superconductivity in Sr2IrO4.

Noncollinear antiferromagnetic order in the buckled honeycomb lattice of magnetoelectric Co4Ta2O9 determined by single-crystal neutron diffraction

Sungkyun Choi, Dong Gun Oh, Matthias J. Gutmann, Shangke Pan, Gideok Kim, Kwanghyo Son, Jaewook Kim, Nara Lee, Sang-Wook Cheong, Young Jai Choi, and Valery Kiryukhin

Phys. Rev. B 102, 214404 (2020) - Published 2 December, 2020

Controlling electric polarization with a magnetic field is of technological and fundamental significance. This can be achieved in magnetoelectric materials. A4B2O9 (A=Fe, Co; B=Nb, Ta) are promising magnetoelectrics because they combine magnetic ions possessing large orbital moments with heavy elements exhibiting strong spin-orbit coupling. Magnetic symmetry is key for the magnetoelectric properties. Neutron diffraction and anisotropic magnetic susceptibility measurements reported in this paper revise the magnetic structure of Co4Ta2O9 and explain its previously puzzling magnetoelectric tensor.

Equation of motion and the constraining field in ab initio spin dynamics

Simon Streib, Vladislav Borisov, Manuel Pereiro, Anders Bergman, Erik Sjöqvist, Anna Delin, Olle Eriksson, and Danny Thonig

Phys. Rev. B 102, 214407 (2020) - Published 7 December, 2020

In ab initio spin dynamics, the effective field acting on a magnetic moment can either be calculated from the energy gradient or from the negative of the constraining field that stabilizes an out-of-equilibrium noncollinear magnetic configuration. Here, the authors show that the constraining field in DFT calculations is not exactly the negative of the effective magnetic field obtained from the energy gradient. They provide a theoretical explanation of this surprising result and discuss the implications for ab initio spin dynamics.

Magnetically induced metal-insulator transition in Pb2CaOsO6

Phys. Rev. B 102, 214409 (2020) - Published 8 December, 2020

Why do some metals suddenly become insulators when their temperature is reduced? At one level, the answer is straightforward: a gap opens up in the electronic spectrum. Yet a variety of different processes can cause a gap to open. In this work, the authors find that the newly synthesized osmium oxide, Pb2CaOsO6, undergoes a metal-to-insulator transition at 80 K, which coincides with the onset of antiferromagnetic ordering. A range of experimental results suggest that the transition is spin-driven and could be a rare example of a Slater transition.

Nonlocal spin Seebeck effect in the bulk easy-plane antiferromagnet NiO

Geert R. Hoogeboom and Bart J. van Wees

Phys. Rev. B 102, 214415 (2020) - Published 14 December, 2020

NiO is an insulating easy-plane antiferromagnet with multiple domains. Its magnon modes with opposite spin become nondegenerate with the application of magnetic field and a subsequent heat gradient results in a net spin current over long distances. After a sign change, both signal strength and noise increase with increasing distance. The authors ascribe this to magnon accumulation at the domain walls, which move with the rotating magnetic field, locally increasing the magnon chemical potential.

Fractons from polarons

John Sous and Michael Pretko

Phys. Rev. B 102, 214437 (2020) - Published 28 December, 2020

Fractons, as a new exotic quasiparticle, have attracted immense attention due to their unique properties. Here, the authors construct a connection between fractons and polarons. This allows them to derive explicitly microscopic models, in which polarons and their two-body bound states, known as bipolarons, map exactly on to fractons and their two-body counterparts, dipoles. As a specific example, the authors show how fractons and dipoles arise from magnetic polarons and bipolarons in hole-doped antiferromagnets, thus providing a route towards their physical realization.

Static magnetic proximity effects and spin Hall magnetoresistance in Pt/Y3Fe5O12 and inverted Y3Fe5O12/Pt bilayers

Phys. Rev. B 102, 214438 (2020) - Published 28 December, 2020

In spintronics and spin caloritronics, the understanding of spin angular momentum transfer across heavy metal/ferromagnetic insulator interfaces is of fundamental importance. There has been much controversy about the presence of magnetic proximity effects at such interfaces. Using element-selective x-ray and angle-resolved magnetotransport measurements, the authors present here a systematic study of Pt/Y3Fe5O12 heterostructures, with different order of the layer stacking resulting in different interface properties. They demonstrate that combined temperature-dependent x-ray and magnetotransport studies are essential to unambiguously confirm or exclude the presence of magnetic proximity effects.

Edge modes in one-dimensional topological charge conserving spin-triplet superconductors: Exact results from Bethe ansatz

Parameshawar R. Pasnoori, Natan Andrei, and Patrick Azaria

Phys. Rev. B 102, 214511 (2020) - Published 23 December, 2020

The authors consider a one-dimensional charge-conserving spin-triplet superconductor with the superconductivity induced by intrinsic attractive pairing interactions between the electrons. Using Bethe ansatz, they show that the system with open boundary conditions exhibits a topological phase characterized by the existence of zero energy bound states localized at the edges. These bound states give rise to degeneracy in the ground-state structure, which results in the existence of fractionalized ¼ spins at the edges.

Fractons from polarons

Phys. Rev. B 102, 214437 (2020) - Published 28 December, 2020

Fractons, as a new exotic quasiparticle, have attracted immense attention due to their unique properties. Here, the authors construct a connection between fractons and polarons. This allows them to derive explicitly microscopic models, in which polarons and their two-body bound states, known as bipolarons, map exactly on to fractons and their two-body counterparts, dipoles. As a specific example, the authors show how fractons and dipoles arise from magnetic polarons and bipolarons in hole-doped antiferromagnets, thus providing a route towards their physical realization.

In spintronics and spin caloritronics, the understanding of spin angular momentum transfer across heavy metal/ferromagnetic insulator interfaces is of fundamental importance. There has been much controversy about the presence of magnetic proximity effects at such interfaces. Using element-selective x-ray and angle-resolved magnetotransport measurements, the authors present here a systematic study of Pt/Y3Fe5O12 heterostructures, with different order of the layer stacking resulting in different interface properties. They demonstrate that combined temperature-dependent x-ray and magnetotransport studies are essential to unambiguously confirm or exclude the presence of magnetic proximity effects.

Phys. Rev. B 102, 214511 (2020) - Published 23 December, 2020

The authors consider a one-dimensional charge-conserving spin-triplet superconductor with the superconductivity induced by intrinsic attractive pairing interactions between the electrons. Using Bethe ansatz, they show that the system with open boundary conditions exhibits a topological phase characterized by the existence of zero energy bound states localized at the edges. These bound states give rise to degeneracy in the ground-state structure, which results in the existence of fractionalized ¼ spins at the edges.
