Determination of Magneto Optical Constants from Multilayer Film Structures

Abstract

A matrix relation is derived for the incident, reflected and transmitted wave vectors for a multilayer stack containing a magneto optic layer. The principle of the method is discussed in many textbooks. However, the dielectric function of a magneto optic medium is a 4th order equation and the resulting matrix is a complex 4 × 4 matrix. Here, the matrix is formulated without approximations and its properties are evaluated numerically.
