Abstract
A magnetoresistive effect element includes a first ferromagnetic layer, a second ferromagnetic layer, and a nonmagnetic metal layer interposed between the first ferromagnetic layer and the second ferromagnetic layer. The first ferromagnetic layer and the second ferromagnetic layer include a Heusler alloy consisting of a CoMnSi alloy. A ratio x of Mn with respect to Co2 in each of the first ferromagnetic layer and the second ferromagnetic layer is 0.7≤x≤1.7. Compositions of the first ferromagnetic layer and the second ferromagnetic layer are different from each other.
