Abstract

The thermal relaxation of the magnetic properties of thin films for hard disk media is studied. The analysed magnetic layers are constituted of ternary and quaternary Co-based alloy with different thickness. The relaxation is analysed with measurement of magnetic viscosity and of coercive field variability. The magnetization switching of the magnetic films is also discussed with the rotational hysteresis analysis. The different stability in the films is discussed with the evolution of the basic processes of magnetization.
