Temperature-invariant magneto-optical Kerr effect in a noncollinear antiferromagnet
Camron Farhang, Weihang Lu, Yuchuan Yao +6
Noncollinear antiferromagnets exhibit anomalous Hall and magneto-optical Kerr effects driven by Berry curvature despite negligible net magnetization, promising ultrafast spintronic…
Direct imaging of a Berry curvature nematic state in a spin-compensated magnet
Weihang Lu, Camron Farhang, Yuchuan Yao +6
Density waves conventionally describe the periodic modulation of charge or spin, yet the spatial modulation of electronic geometry has remained elusive. Here, we report subtle micr…
Fit-Free Optical Determination of Electronic Thermalization Time in Nematic Iron-Based Superconductors
Alexander Bartenev, Roman Kolodka, Ki-Tae Eom +6
We present a nematic response function model (NRFM) for fit-free direct extraction of the characteristic time of ultrafast electronic thermalization in iron-based superconductors,…
Electrical Characterization of High-k (k>115) Crystalline SrTiO3 (STO) thin film integration with GaN with Nanomembrane Transfer Process
Md Tahmidul Alam, Kyoungjun Lee, Guangying Wang +2
High-k (115), crystalline SrTiO3 (STO) thin film was transferred on GaN for potential applications in power devices (transistor and diodes) by nanomembrane transfer method and the…
Unusual dependence on the angle of magnetic field for the spin Hall magnetoresistance of monodomain epitaxial BiFeO3 thin films
Yongjian Tang, Pratap Pal, Matthew Roddy +7
Spin Hall magnetoresistance (SMR) measurements provide a way to probe the surface spin structure of insulating magnetic materials. Such measurements produce resistance signals of t…
Twisted oxide membrane interface by local atomic registry design
Min-Su Kim, Kyoungjun Lee, Ryo Ishikawa +9
Interplay of lattice, orbital, and charge degrees of freedom in complex oxide materials has hosted a plethora of exotic quantum phases and physical properties. Recent advances in s…
