Abstract
There is provided a magnetoresistive film in which an interlayer coupling field H is minimized and a large regeneration output is produced. A multilayered film includes an underlayer , an antiferromagnetic layer , a pinned magnetic layer , a nonmagnetic middle layer , and a free magnetic layer , the pinned magnetic layer comprises a first soft magnetic layer and a second soft magnetic layer formed of soft magnetic materials and an antiparallel coupling middle layer , formed between the soft magnetic layers, for coupling the magnetizations of the soft magnetic layers to each other in opposite directions, the antiferromagnetic layer comprises an ordered-form antiferromagnetic material including Mn, and a second underlayer as a direct substrate of the antiferromagnetic layer comprises a metal selected from the group consisting of Ru, Os, Re, Tc, Cd, Ti, Zn, Al, Au, Ir, Pd, Pt, Rh, Ag, Nb, Mo, W, V, and &agr;-Ta or an alloy including an element of the selected metal.
