Zusammenfassung:PROBLEM TO BE SOLVED: To provide a magnetoresistive multiple layer device that is temperature-independent of and highly sensitive to an external field. SOLUTION: A stack has a first magnetic layer, a first intermediate layer, and a second magnetic layer arranged in this order toward a magnetic resistive stack, in which the first magnetic layer and the second magnetic layer are separated off from each other through the interposition of the non-magnetic first intermediate layer and ferromagnetically cross-coupled with each other, and the scattered-magnetic-field coupling of the two magnetic layers is directed oppositely to the ferromagnetic cross-coupling.
