The influence of surface anisotropy on FMR in bulk metal ferromagnets

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The subject of this work is an investigation of the effects of surface anisotropy in ferromagnetic resonance (FMR) in bulk metal samples. The surface anisotropy (with arbitrary values of the constantK s) is included in the equations of the macroscopic theory of FMR in the so called parallel experimental configuration. Its influence on the inflexion linewidth and on the resonance field correction is illustrated graphically for a typical value of the exchange-conductivity parameterE. It is also shown that experimental determination of the resonance parameters for samples with different surface orientations enables one to decide whether the Néel anisotropy dominates in the surface conditions.
