Evidence of Crystal-Field-Mediated Anisotropic Orbital Rashba Effect in Epitaxial Ru/FM Heterostructure
Yu Zhang, Wenhao Niu, Yumin Yang +5
Electrical generation of orbital angular momentum provides a promising route to current-induced torques, yet effective control of orbital Rashba textures still remains challenging,…
Effects of Impurity Scattering on Orbital Hall Conductivity and Orbital Transport in Ru-based Alloys
Yumin Yang, Yanxu Chen, Wenqi Xu +1
The role of impurity scattering in the generation and transport of orbital current remains less established than in conventional spin Hall systems. Here we investigate Ru-based non…
Absence of Orbital Hall Magnetoresistance in Nonmagnet/Ferromagnet Bilayers with Large Orbital Torque
Yumin Yang, Wenqi Xu, Na Lei +3
We report the absence of orbital Hall magnetoresistance (OMR) in nonmagnet/ferromagnet bilayers, challenging the general assumption that orbital transport mimics spin transport. De…
All-Optical Manipulation of Band Gap Dynamics via Electron-Phonon Coupling
Jicai Zhang, Tien-Dat Tran, Ziwen Wang +5
The electron-phonon coupling (EPC) is a ubiquitous interaction in condensed systems and plays a vital role in shaping the electronic properties of materials. Yet, achieving coheren…
