摘要:
A thin film magnetic head includes an upper core layer and a lower core layer which are made of an Fe—M—O alloy, an Fe—M—T—O alloy or an NI—Fe—X alloy so that the upper core layer has a high saturation magnetic flux density, low coercive force and high resistivity, and the lower core layer has a lower saturation magnetic flux density than the upper core layer, low coercive force, high resistivity, and a low magnetostriction constant. Also the lower core layer is formed so that the thickness gradually decreases toward both side ends, and a gap layer can be formed on the lower core layer to have a uniform thickness. Since the lower core layer is formed by sputtering, a material having excellent soft magnetic material can be used, thereby enabling recording at high frequency.

A hard magnetic material contains Co as a main component, at least one element Q of P, C, Si and B, and Sm, and an amorphous phase and a fine crystalline phase. The texture of the hard magnetic material contains 50% by volume or more of fine crystalline phase having an average crystal grain size of 100 nm or less, and has a mixed phase state containing a soft magnetic phase and a hard magnetic phase. Further, anisotropy is imparted to the crystal axis of the hard magnetic phase.
