Abstract
A magnetoresistive film is disclosed which has a layered structure comprising a first ferromagnetic layer, a second ferromagnetic layer, a nonmagnetic conductive layer interposed between the first and second ferromagnetic layers, and an antiferromagnetic layer coupled with one of the first and second ferromagnetic layers. The antiferromagnetic layer comprises an antiferromagnetic material selected from an antimony-base alloy, fluoride, an FeRh-base alloy, FeS, an IrMnCo-base alloy and a CrAl-base alloy.
