PURPOSE:To develope a 'Sendust(R) high permeability alloy for a magnetic head having excellent heat resistance and high reliability by incorporating specific small amounts of at least one kind among W, Re, Ta, Mo, Nb, Ir and Zr into 'Sendust(R). CONSTITUTION:The title alloy is obtained with containing 0.05 to 2%, by weight, of at least one kind among metallic elements such as W, Re, Ta, Mo, Nb, Ir and Zr into 'Sendust(R) contg. 8 to 12% Si, 4 to 7% Al and the balance Fe. By the addition of these metallic elements, the heat resistance of a 'Sendust(R) thin film is improved to increase the deposition temp. depending on glass at the time of manufacturing a magnetic head with the 'Sendust(R) thin film, by which the high permeability magnetic head having excellent corro sion resistance, moisture resistance, etc., can be manufactured. |
