  • Abstract
    A method for controlling the domain structure by improving the multilayerization of Fe-Si-Ru alloy, Ni-Fe alloy and SiO2 to improve the reproduction sensitivity of single-pole perpendicular magnetic heads. Measurements of the permeability of the Fe-Si-Ru multilayered film before and after patterning revealed that before patterning it was almost constant at 2200 up to an intermediate SiO2 layer thickness of 30 nm, and that it decreased above that point, but after patterning, the permeability improved as the SiO2 layer thickness increased and reached a maximum of 1000 at 20 nm.
