ABSTRACT:
A soft magnetic layer is made of nickel iron alloy containing crystals of the face-centered cubic lattice and crystals of the body-centered cubic lattice. The face-centered cubic lattice serves to establish a soft magnetic property in the nickel iron alloy. The body-centered cubic lattice contributes to reduction in the electric resistance of the magnetoresistive film as well as to improvement of the magnetoresistive ratio of the magnetoresistive film. Even if the magnetoresistive film is further reduced in size, the magnetoresistive film can sufficiently be prevented from suffering from an increase in the temperature. Even if a sensing current of a larger current value is supplied to the magnetoresistive film, the magnetoresistive film is reliably prevented from deterioration in the characteristics as well as destruction.
