Abstract
A soft magnetic film is formed which is represented by the formula (FeNi)Mo, in which 0.65≦x≦0.75 and x+y=1 are satisfied when x and y are on a mass percent ratio basis, and 0<b≦5 and a+b=100 are satisfied when a and b are on a mass percent basis, and by using this soft magnetic film, a lower core layer and/or an upper core layer is formed. Accordingly, a saturated magnetic flux density of 1.6 T or more and a resistivity of 40 μΩ·cm or more can be obtained, and hence a thin film magnetic head having a small loss in a high frequency signal region can be provided.
