Experimental Aspects of Cavity Optomagnonics

Abstract

Cavity optomagnonics emerged as a route to enhance inherently weak interaction between light and solid-state magnons by using an optical cavity. In the early stage the light-magnon interaction was investigated using a ferrimagnetic sphere, exhibiting rich physical phenomena not only the enhanced light-magnon interaction but the ones such as nonreciprocal Brillouin scaterring. Here we review the progress of cavity optomagnonics from an experimental perspective.
