Abstract

Ferromagnetic resonance measurements were carried out for single crystalline Co2MnAl thin films as a function of the angle between applied external magnetic field and normal of the film surface. In- and out-of-plane angular dependence of the resonance field and only out-ofplane angular dependence of the linewidth of FMR spectra were analyzed using the Landau-Lifshitz-Gilbert equation. The easy and hard axes were determined by analyzing the in-plane angular dependence of resonant field. The films annealed at various temperatures showed four-fold magnetic anisotropy symmetry and the damping factor was estimated from the analysis of the angular dependency of FMR spectra.
