Abstract

The rotation of the plane of polarization in films of a 35% nickel in iron alloy was determined as a function of the quasi-static magnetization reversal process related to the angle of incidence and azimuth of the transmitted plane polarized white light. The magnetooptic hysteresis loops determined in this manner offer direct information on the coercivity, magnetization, susceptibility, and anisotropy of ferromagnetic films. It is shown that a modified form of Kundt’s empirical law can account for the experimentally measured Faraday rotation by introducing the dependence of the rotation upon the optical properties of the films, the azimuth, and the angle of incidence of the light.
