EASY-AXIS DISTRIBUTION IN DISORDERED MAGNETIC-MATERIALS

We describe a model applicable to disordered magnetic materials with a large ratio of anisotropy to interaction, which includes interactions between magnetic moments through a mean-held approximation and provid es expressions useful to determine the magnetic easy-axis distribution , and also the magnitude of interaction and the direction of the mean field. The angular dependencies of magnetic remanences parallel and pe rpendicular to the applied field are examined, resulting in good agree ment with experiments found in the literature. The dependence of the C urie temperature on the easy-axis distribution and on interaction stre ngth is also analyzed.
