AMORPHOUS SOFT MAGNETIC THIN FILM AND PERPENDICULAR MAGNETIC RECORDING MEDIUM USING IT

摘要

PROBLEM TO BE SOLVED: To maintain the coercive force Hc of a Co-Zr-based amorphous soft magnetic thin film at a low level when the thickness of the film is reduced.;SOLUTION: In the amorphous soft magnetic thin film composed of a Co-Zr- based material containing added Ti, the adding rate of the Ti is adjusted to ≥2.5 atom%.;COPYRIGHT: (C)2001,JPO
