Influence of magnetic film thickness on the escape anisotropy of the electrons emitted in the presence of a stripe domain structure

Abstract

Angular distributions of the escape of electrons, emitted by the surface of a magnetic film containing a stripe domain structure (SDS) are calculated. It is shown for the films of cobalt and ferrite-garnet that the film thickness and the parameters of the magnetic materials significantly influence the conditions of escape blocking and channelling of the electrons near the sample surface. A primitive model of particle channelling along the domain boundary gives a qualitatively correct description of the thickness influence on the shadow size and the critical channelling angle along the boundary of a stripe domain.
