Magnetowiderstandseffekt-Element

摘要

A magnetoresistance effect element comprises the multilayer formed by alternately stacking magnetic and nonmagnetic layers (2, 3). The magnetic layers (3) containing at least two magnetic elements selected from a group of magnetic elements consisting of Fe, Co and Ni. Any two magnetic layers adjacent to each other with one of the nonmagnetic layer interposed therebetween are antiferromagnetically coupled under a condition where a magnetic field is not substantially applied thereto.
