Abstract

The influence of domain walls on magneto-optic effect of the double-layered films is investigated. A method to cut the domain walls into a set of parallel thin-limit layers is introduced.Thus, the problems of light reflected by and transmitting through the domain walls are equivalent to those by thin-limit multilayer systems. The equation of Kerr rotation angle induced by domain walls is deduced. It is found that the Kerr rotation angle depends on the thickness of domain walls in the double-layered films.
