摘要：
A ferromagnetic film which comprises ferromagnetic metal in which an oxide phase is present, a method for producing it, and a magnetic head in which said ferromagnetic film is used are disclosed. The ferromagnetic metal includes iron and cobalt and the oxide phase contains preferably at least one element selected from IVa, Va and VIa group elements.
