Model of the magnon Kerr effect in a highly anisotropic ferromagnet
Davit Petrosyan, Hiroki Matsumoto, Hanchen Wang +3
The magnon Kerr effect is a nonlinear phenomenon that occurs universally in any ferromagnet with finite magnetic anisotropy. It manifests itself as a magnon population-dependent ch…

Coherent control of domain wall dynamics offers a route to fast manipulation of magnetic textures beyond thermally activated motion. We demonstrate resonant excitation of linear an…
Disambiguating electrical detection of magnetization dynamics in magnetic insulators
Hanchen Wang, William Legrand, Shangyuan Wang +6
Electrical detection of magnetization dynamics in magnetic insulators underpins both fundamental studies of magnon transport and the development of low-loss magnonic devices. In he…
