ABSTRACT:
This invention concerns a magnetoresistive head for converting a change in magnetic field into a change in resistance by virtue of a spin valve magnetoresistive effect. This magneto-resistive transducer has superposed sequentially on a substrate an underlayer formed of two layers consisting of a tantalum film and a nickel iron based alloy film, an antiferromagnetic layer, a first soft magnetic layer, a nonmagnetic metal layer, and a second soft magnetic layer in the order mentioned.
