A magnetic head in which a pair of magnetic core halves are abutted to each other, at least one of said core halves being formed by an oxide magnetic core portion and a soft magnetic alloy thin film portion provided on said oxide magnetic core portion, said soft magnetic alloy thin film portion being formed of a first film portion formed of an Fe-GA-Si system alloy containing a certain amount of Ru, and provided adjacent to said oxide magnetic core portion, and a second film portion formed of a soft magnetic alloy having different composition from said first film portion and facing to another magnetic core half to define a magnetic gap therebetween, the boundary surface between the Fe-Ga-Si system soft magnetic thin film and said oxide magnetic core portion being substantially parallel to a gap surface in the vicinity of the magnetic gap.
- 2. A magnetic head according to claim 1, said second film portion being formed of an Fe-GA-Si system alloy containing a lesser amount of Ru than said certain amount.
