摘要：
A magnetic thin film consisting essentially of Fe, Al and Si and further containing oxygen has high magnetic permeability and high hardness without lowering the magnetic properties such as saturation magnetic flux density or coercive force.The magnetic thin film has an increased specific resistivity and a lowered eddy current loss in the high frequency region and is suitable for a core material of magnetic transducer heads used in a high frequency region.The magnetic thin film is prepared by, for example, physical vapor deposition or ion implantation.
