SOFT MAGNETIC THIN-FILM BASED ON CO-NI-FE, MANUFACTURING THE SAME, AND MAGNETIC HEAD AND MAGNETIC MEMORY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a soft magnetic thin-film having a highly saturated magnetization and high specific resistance, and method of manufacturing the same, to provide a magnetic head and magnetic memory using the soft magnetic thin-film. ;SOLUTION: At least one of a lower soft magnetic layer 13 or an upper soft magnetic layer 18 of a magnetic head forming a magnetic circuit is formed by a soft magnetic thin-film based on a Co-Ni-Fe having S of an atomic ratio 0.5-4at% against an alloy Co-Ni-Fe consisting of Co of an atomic ratio, 30-90%, Ni of less than 40%, and Fe of less than 40%. The soft magnetic thin-film is formed through an electrodeposition from a plating solution consisting of each metallic salt of Co, Ni, and Fe, and also from a Co-Ni-Fe plating solution consisting of an organosulfur compound.;COPYRIGHT: (C)1998,JPO
