ABSTRACT:
A soft magnetic thin film for magnetic head has high saturation magnetization and at the same time high resistivity. There are provided a method of manufacturing the soft magnetic thin film and a magnetic head and a magnetic storage unit which use the soft magnetic thin film. At least one of lower and upper soft magnetic layers of magnetic head which define a magnetic circuit is formed of a soft magnetic thin film having as a main constituent a Co--Ni--Fe alloy consisting of 30 to 90 at % Co, less than 40 at % Ni and less than 40 at % Fe and containing at least S by 0.5 to 4 at %. The soft magnetic thin film is formed from a Co--Ni--Fe alloy plating solution containing metal salts of Co, Ni and Fe and additionally containing a sulfur system organic compound through electrodeposition process.
