Abstract
The thickness dependence of soft magnetic properties was investigated for Fe-Si and Fe-Si-N films. The results were compared with the predic tions of Hoffmann's ripple theory. It was suggested that the optimum s oft magnetic properties can be obtained for films with thickness aroun d 2000 angstrom. Reducing the grain size as well as suppressing the co lumn growth in the films lead to a way to improve the magnetic softnes s of Fe-based films, and the nitrogenation of the films is an effectiv e method to realize this purpose.
