ABSTRACT:
A magnetoresistive head having a soft magnetic layer which comprises a Co--Fe--Ta amorphous magnetic material and applies a transverse bias magnetic field to a magnetoresistive layer. The amorphous magnetic material has such properties that the induced anisotropy is readily attained in the lateral direction, the rate of magnetoresistance change (.DELTA..rho./.rho.) is low, the magnetization stability in the lateral direction is enhanced, and Barkhausen noise is decreased. Since tantalum, one of the amorphous elements, sets the magnetostriction toward the minus side while iron (Fe) sets the magnetostriction toward the plus side, it is possible to control the magnetostriction of the soft adjacent layer by selecting the iron (Fe) concentration and to prevent the magnetoelastic effect from disturbing the magnetization stability in the lateral direction.
