Chemical migration and dipole formation at van der Waals interfaces between magnetic transition metal chalcogenides and topological insulators

Brenton A. Noesges, Tiancong Zhu, Jacob J. Repicky, Sisheng Yu, Fengyuan Yang, Jay A. Gupta, Roland K. Kawakami, and Leonard J. Brillson

Phys. Rev. Materials 4, 054001 (2020) - Published 8 May, 2020

Interfaces between topological insulators (TIs) and magnetic materials, including 2D van der Waals magnets, are currently generating enormous interest, due to phenomena such as the quantum anomalous Hall effect. Many of the magnets employed contain reactive and diffusive elements such as Mn, however, raising serious materials challenges. This work explores the interface between Bi $_{2}$ Se $_{3}$ and Mn and MnSe, revealing chemical and electronic changes at the interface depending on how Mn is deposited. Mn deposited without excess selenium shows Se out-diffusion from Bi $_{2}$ Se $_{3}$ to the Mn. Supplying excess Se alongside Mn prevents this Se out-diffusion, but the interface becomes affected by a negative surface dipole. This dipole forms due to preferential creation of $α$ -MnSe(111) over the 1T-MnSe $_{2}$ phase. This study shows that chemical diffusion and dipole formation are important for Mn-Bi $_{2}$ Se $_{3}$ and MnSe $_{2 - x}$ -Bi $_{2}$ Se $_{3}$ interfaces and must generally be considered at TI/Mn chalcogenide interfaces.

Unexpected crystalline homogeneity from the disordered bond network in $La (C r_{0.2} M n_{0.2} F e_{0.2} C o_{0.2} N i_{0.2}) O_{3}$ films

Matthew Brahlek, Alessandro R. Mazza, Krishna Chaitanya Pitike, Elizabeth Skoropata, Jason Lapano, Gyula Eres, Valentino R. Cooper, and T. Zac Ward

Phys. Rev. Materials 4, 054407 (2020) - Published 12 May, 2020

The ability to host five or more cations on a sublattice within a single crystal oxide offers new opportunities to design materials with tailored bonding environments and functional properties. La(Cr $_{0.2}$ Mn $_{0.2}$ Fe $_{0.2}$ Co $_{0.2}$ Ni $_{0.2}$ )O $_{3}$ , which straddles the phase-boundary between orthorhombic and rhombohedral, is expected to exhibit a tremendous level of local distortion. Despite this, La(Cr $_{0.2}$ Mn $_{0.2}$ Fe $_{0.2}$ Co $_{0.2}$ Ni $_{0.2}$ )O $_{3}$ is found to exhibit a surprisingly well-ordered lattice, which homogeneously favors the orthorhombic phase. The observation of long-range order that emerges out of a configurationally complex local bonding environment suggests unforeseen cooperative effects at play in entropy stabilized materials.

Correlating magnetic structure and magnetotransport in semimetal thin films of ${Eu}_{1 - x} {Sm}_{x} {TiO}_{3}$

Zach Porter, Ryan F. Need, Kaveh Ahadi, Yang Zhao, Zhijun Xu, Brian J. Kirby, Jeffrey W. Lynn, Susanne Stemmer, and Stephen D. Wilson

Phys. Rev. Materials 4, 054411 (2020) - Published 15 May, 2020

In magnetic Weyl semimetals, anomalous magnetotransport phenomena arise as the result of broken time reversal symmetry and a particular type of topologically nontrivial band structure. Here, the authors report neutron scattering studies of one such magnetic Weyl semimetal candidate material, Eu $_{1 - x}$ Sm $_{x}$ TiO $_{3}$ . The formation and character of magnetic order are tracked under applied magnetic field as a means of understanding the unusual magnetoresistance in this compound. Direct correlations between a field-driven spin-flop transition and depth-dependent magnetism are discussed as the origins of the previously reported anisotropic magnetoresistance and topological Hall effect for this material.

In situ TEM observation of nanodomain mechanics in barium titanate under external loads

Takashi Sumigawa, Ken Hikasa, Akihisa Kusunose, Hiroki Unno, Kairi Masuda, Takahiro Shimada, and Takayuki Kitamura

Phys. Rev. Materials 4, 054415 (2020) - Published 19 May, 2020

The difficulty in nanomechanical testing has hindered real-time in-situ observation of stress-induced domain wall motions in ferroelectrics. By fabricating rationally designed specimens, the authors conducted controlled nanoscale tensile and bending tests, and showed real-time domain wall motions in ferroelectrics. They directly imaged domain wall motions in transmission electron microscope and find the mechanical criterion that governs the behavior of domain walls. The paper provides information on how to control domain wall dynamics from an engineering standpoint.

Anisometric mesoscale nuclear and magnetic texture in sintered Nd-Fe-B magnets

Ivan Titov, Dirk Honecker, Denis Mettus, Artem Feoktystov, Joachim Kohlbrecher, Pavel Strunz, and Andreas Michels

Phys. Rev. Materials 4, 054419 (2020) - Published 29 May, 2020

Nd-Fe-B magnets are an important class of functional materials which find widespread technological application. Neutron scattering experiments suggest the presence of an anisometric mesoscale structure in textured Nd-Fe-B magnets. Comparison of the neutron data to a microstructural model based on the superquadric form factor allows the estimation of the shape and of lower bounds for the size of the structure, the origin of which remains unknown. It is a challenge for future research to find out whether the anisotropic scattering pattern is due to some arrangement of preferentially oriented particles or due to larger-scale structural or compositional inhomogeneities.

Monoclinic semimetal IrSi synthesized under high pressure above 25 GPa: Crystal structure, electronic, and magnetic properties

Y. Fujishiro, N. Kanazawa, T. Shinmei, M. Nishi, T. Nakajima, T. Arima, D. Hashizume, M. S. Bahramy, T. Irifune, and Y. Tokura

Phys. Rev. Materials 4, 055002 (2020) - Published 15 May, 2020

Transition metal monosilicides exhibit diverse physical properties depending on their crystal structures. Regarding IrSi, only the MnP-type orthorhombic form has been known so far. In this paper, the authors report a successful synthesis of a monoclinic phase through high-pressure high-temperature treatment above 25 GPa, while the theoretically predicted B20-type cubic structure has not been identified up to 48 GPa. Magneto-transport measurements reveal a semimetallic nature of the monoclinic form with a low carrier density of ~1019 /cm $^{3}$ . Combined with large Rashba spin splitting of surface electronic bands, monoclinic IrSi may offer a potential material platform for versatile spintronic applications in the two-dimensional limit.

Ionic liquid dynamics in nanoporous carbon: A pore-size- and temperature-dependent neutron spectroscopy study on supercapacitor materials

Mark Busch, Tommy Hofmann, Bernhard Frick, Jan P. Embs, Boris Dyatkin, and Patrick Huber

Phys. Rev. Materials 4, 055401 (2020) - Published 27 May, 2020

Ionic liquids imbibed in nanoporous carbons are promising hybrid materials for electrochemical energy storage, conversion and harvesting. These functionalities crucially depend on the ionic mobility in the pore space. The authors demonstrate that quasielastic neutron scattering, specifically the so-called fixed energy window experimental technique, is particularly suitable for a fast access of the confined ionic liquid’s dynamic landscape as a function of pore-size and temperature. Compared to the bulk they find reduced self-diffusion mobilities. However, despite this slowing-down, the temperature range of the liquid state upon nanoconfinement is remarkably extended to much lower temperatures, which is beneficial for potential technical applications of such liquid-infused solids.

Understanding the molecular origin of shear thinning in associative polymers through quantification of bond dissociation under shear

Irina Mahmad Rasid, Jorge Ramirez, Bradley D. Olsen, and Niels Holten-Andersen

Phys. Rev. Materials 4, 055602 (2020) - Published 11 May, 2020

Transient network theory is the state of the art for understanding the mechanical response of associative networks. However, the predictions of the models are difficult to verify in the absence of direct observations of the bond states. This manuscript introduces a method to quantitatively measure force-induced bond dissociation in associative networks through the design of an opto-mechanically coupled model polymer system and a rheo-fluorescence set-up. The findings show that shear thinning in the model associative polymers cannot be explained by classical theories, and likely involves alternative modes as suggested by newer models.
