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…

Chiral dual spin currents field-free perpendicular switching by altermagnet RuO2
Gengchen Meng Qi Sun, Zhicheng Xie, Yumin Yang +3
Conventional spintronic mechanisms, such as spin-transfer and spin-orbit torques based on the spin current, rely on breaking time-reversal symmetry to manipulate magnetic moments.…
