The Sendust MIG (metal-in-gap) head has been developed for high density recording systems. Aloxidization at the boundary between the Sendust film and MnZn-ferrite, however, degrades the soft magnetic properties and insertion of Ni-Fe film between them is effective to rectify this problem. In the present paper, the effects of Ni-Fe film insertion are investigated in detail and the following results obtained: 1) X-ray diffraction intensity of (110) plane for the Sendust film on Ni-Fe/MnZn-ferrite is stronger than that on MnZn-ferrite. 2) Ni atoms in Ni-Fe film diffuse into the Sendust film with annealing at over 550°C. 3) Little degradation of permeability and coercivity is observed for the Sendust film containing Ni less than 1.4 wt.%
