ABSTRACT:
The present invention provides, by combining as the composition of the soft magnetic thin film transition metals and two different kinds of metalloid (semiconductor) elements, herein B, C and Si, a novel amorphous soft magnetic thin film having a structure wherein two phases, namely the ferromagnetic amorphous phase and the non-magnetic amorphous phase and finely dispersed for realizing a soft magnetic thin film that is superior in high frequency characteristics and that may be applied to the magnetic head technology for short wavelength recording that may be advantageously employed with a high coercive force medium.
