MAGNETKOPF UND VERFAHREN ZU SEINER HERSTELLUNG

摘要

A magnetic head including a magnetic film formed on a substrate. The magnetic film contains a Co-rich Fe alloy having a face-centered cubic phase in which the <100> axis has been oriented in a direction perpendicular to the film surface, an insulating film formed on the magnetic film, and coils buried in the insulating film so as to generate a magnetic field. The Co-rich Fe alloy contains 15 to 24 atomic % of Fe. The magnetic head is manufactured by forming a magnetic film on a substrate, the magnetic film containing a Co-rich Fe alloy having a fcc phase in which the <100> axis has been oriented in a direction perpendicular to the film surface. Next, an insulating film having coils for generating a magnetic field buried therein is formed on the magnetic film.
