Abstract
The present invention provides a novel soft magnetic material superior in corrosion resistance which contains (a) a ferromagnetic metal and (b) a carbide of a ferromagnetic metal and/or a silicide of a ferromagnetic metal with at least one of (c) an amorphous carbon and/or an amorphous silicon and (d) a hydrocarbon polymer and/or a silicone polymer and which contains carbon atoms in an amount of 15 atomic % or less, preferably 9-15 atomic %, preferably prepared by the simultaneous vapor deposition of a ferromagnetic metal and a polymer.
