Measurement of magneto-optical constants of RE-TM films by frequency doubling method

Abstract

Frequency doubling method has been applied to measure polar Kerr rotation and ellipticity. Magneto -optical (MO) constants of some GdCo and TbFeCo films were obtained. The optical performance of A1N TbFeCo / glass bilayer structure calculated with the measured MO constants agrees quite well with the experimental results.
