Optical Hall response in spin-orbit coupled metals: Comparative study of magnetic cluster monopole, quadrupole, and toroidal orders

T Sato, Y Umimoto, Y Sugita, Y Kato, Y Motome - Physical Review B, 2021 - APS
The optical Hall response is theoretically studied for spin-orbit coupled metals with ferroic
orders of cluster-type magnetic multipoles. We find that different magnetic multipoles give …
