Electric-field induced magnetization in YIG observed by Faraday rotation

Abstract

We studied the electric-field induced magnetization caused by the magnetoelectric effect in YIG. The magnetization was observed as the Faraday rotation of a transmitted continuous-wave probe light. From the observed dependence of the Faraday-rotation amplitude on the electric and magnetic fields, it was found that the two components linear and quadratic in the electric field coexist at low temperatures.
