Abstract
The effect of magnetostriction and strip width on the permeability and the domain structure of strip films is investigated in detail. The hard axis permeability at 1 MHz of strip films of 6–12 μm width directly relates to the volume of a easy axis domain. The anisotropic stress along the hard axis calculated from the result of x‐ray diffraction measurement is tensile and increases up to 17–26 kg/mm2 for 6 μm width. These values are in good agreement with that calculated from the permeability dependence on magnetostriction. The permeability of the films on the stepped surface can be explained with the combination of that on the flat surface and that on the slope surface. The permeability of the samples of head pole configurations can be understood separately for the yoke region and the pole tip region, and considered as the combination of that of both regions.
