Title:
MANUFACTURE OF SOFT MAGNETIC ALLOY PLATED THIN FILM AND THE FILM AND THIN-FILM MAGNETIC HEAD
Document Type and Number:
Japanese Patent JP2000208355
Kind Code:
A
Abstract:
To obtain a soft magnetic alloy plated thin film with high saturated magnetic flux density, superior soft magnetic characteristics, high specific resistance, and superior write and read characteristics.
Each dihydric ion of Co, Ni, and Fe is supplied to plating liquid by salt containing each dihydric ions of Co, Ni, and Fe, and at least one kind from among molybdic acid ion, tungstic acid ion, and vanadic acid ion, and chrome (III) ion is doped to the plating liquid. In this case, by having electric plating conducted in the plating liquid in which the ion concentration of the dopant ion is 1×10-5 mol/l or higher and 2×10-4 mol/l or lower so that a soft magnetic alloy plated thin film can be formed.
