Strain-induced orbital energy shift in antiferromagnetic RuO2 revealed by resonant elastic x-ray scattering

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Benjamin Gregory, Jörg Strempfer, Daniel Weinstock, Jacob Ruf, Yifei Sun | Summary: In its ground state, RuO2 was long thought to be an ordinary metallic paramagnet. Recent neutron and x-ray diffraction revealed that bulk RuO2 is an antiferromagnet (AFM) with TN above 300 K. Furthermore, epitaxial […]

Nonvolatile Electric-Field Control of Inversion Symmetry

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Lucas Caretta, Yu-Tsun Shao, Jia Yu, Antonio B. Mei, Bastien F. Grosso | Summary: In condensed-matter systems, competition between ground states at phase boundaries can lead to significant changes in material properties under external stimuli, particularly when these ground states have different crystal symmetries. A key […]

Direct visualization of electronic transport in a quantum anomalous Hall insulator

Kavli Affiliate: Katja C. Nowack | First 5 Authors: G. M. Ferguson, Run Xiao, Anthony R. Richardella, David Low, Nitin Samarth | Summary: A quantum anomalous Hall (QAH) insulator is characterized by quantized Hall and vanishing longitudinal resistances at zero magnetic field that are protected against local perturbations and independent of sample details. This insensitivity […]

Origins of transverse voltages generated by applied thermal gradients and applied electric fields in ferrimagnetic-insulator/heavy-metal bilayers

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Arnab Bose, Rakshit Jain, Jackson J. Bauer, Robert A. Buhrman, Caroline A. Ross | Summary: We compare thermal-gradient-driven transverse voltages in ferrimagnetic-insulator/heavy-metal bilayers (Tm3Fe5O12/W and Tm3Fe5O12/Pt) to corresponding electrically-driven transverse resistances at and above room temperature. We find for Tm3Fe5O12/W that the thermal and electrical effects […]
