Identifying intrinsic and extrinsic mechanisms of anisotropic magnetoresistance with terahertz probes
Ji-Ho Park, Hye-Won Ko, Jeong-Mok Kim +7
Identifying the intrinsic and extrinsic origins of magneto-transport in spin-orbit coupled systems has long been a central theme in condensed matter physics. However, it has been e…
Long-Range Orbital Magnetoelectric Torque in Ferromagnets
Dongwook Go, Daegeun Jo, Kyoung-Whan Kim +6
While it is often assumed that the orbital response is suppressed and short-ranged due to strong crystal field potential and orbital quenching, we show that the orbital magnetoelec…
