ABSTRACT:
In a magnetoresistive magnetic head which has a permalloy film (2, 22) as the magnetoresistive film and also has a shunt film for applying a transverse biasing magnetic field, an Nb film (3, 23) is formed as the shunt film by the electron-beam evaporation method to increase the heat resistance of the magnetoresistive element, thus making it possible to increase the temperature at which the magnetic head is manufactured.
