Measurement of DC Magneto-Optical Kerr Effect with Sensitivity of $10^{-7}\text{Rad}/\sqrt{\text{Hz}}$

Junying Ma, Feng Gu, Ying Xu +4

A high-sensitive DC Magneto-Optical Kerr Effect (MOKE) apparatus is described in this letter. Via detailed analysis on several dominating noise sources, we have proposed solutions…
