ABSTRACT:
A material for magnetic pole for attaining a writing head generating an intense recording magnetic field, and a structure and a manufacturing method therefor. The thin film magnetic head includes a magnetic pole layer having a plated magnetic layer containing Co, Ni and Fe formed on a plated underlayer of a sputtered magnetic layer containing Co, Ni and Fe. The CoNiFe magnetic layer having a composition: 40 wt %≦Co≦70 wt %, 10 wt %≦Ni≦25 wt % and 10 wt %≦Fe≦30 wt % and a peak intensity ratio in the X-ray diffraction of I(200)/I(111)≧0.5 and I(110)/I(111)≧1 (defining peak intensities for the face-centered cubic fcc (111) face, fcc (200) face and the body-centered cubic bcc (119) face as: I(111), I(200), I(110)).
