Abstract:
A magnetoresistive transducer comprising:a multilayer having at least a soft magnetic layer and a conductive nonmagnetic layer alternately laminated therein, wherein said soft magnetic layer is a multilayer superposed structure including a (Co.sub.y Fe.sub.100-y).sub.100-x Z.sub.x alloy layer, wherein Z represents boron, and x and y represent atomic fractions (at %), and an alloy layer containing at least Ni and Fe, said (Co.sub.y Fe.sub.100-y).sub.100-x Z.sub.x alloy layer of said soft magnetic layer bordering on said nonmagnetic layer and having a face-centered cubic lattice structure with a d spacing smaller than a d spacing of a Co.sub.y Fe.sub.100-y alloy; anda pair of electrodes formed on said multilayer for allowing a sense current to pass through said multilayer.
