A magnetic thin film for a magnetic head, comprising:
- an iron film layer formed on a substrate and including N chemically not combined with Fe;
- and
- a sendust film layer formed on said iron film layer and having a (111) plane orientation parallel to said sendust film layer.
A magnetic head having a magnetic circuit formed only of a magnetic thin film, said magnetic thin film comprising;
- an iron film layer formed on a substrate and including N chemically not combined with Fe;
- and
- a sendust film layer formed on said iron film layer and having a (111) plane orientation.
A method of manufacturing a magnetic thin film for a magnetic head, comprising the steps of:
- forming an iron film layer including N chemically not combined with Fe on a substrate using plasma in nitrogen atmosphere in a film formation apparatus;
- and
- forming a sendust film layer having a (111) plane orientation on said iron film layer in vacuum in the same film deposition apparatus.
A magnetic thin film for a magnetic head, comprising:
- an iron film layer formed on a substrate and including N chemically not combined with Fe;
- and
- a sendust film layer formed on said iron film layer and having a (111) plane orientation parallel to said sendust film layer,
- wherein said iron film layer has a resistivity of 50 to 300 .mu..OMEGA..multidot.cm, a crystal grain size of less than 20 nm, and a thickness of 30 to 100 nm.
