Abstract:
1. A magnetoresistive effect element comprising: a first electrode layer of a crystalline material; a first base layer of a conductive amorphous material formed over the first electrode layer; a second base layer of a crystalline material formed over the first base layer and having a larger crystal grain diameter than a crystal grain diameter of the crystalline material forming the first electrode layer; an antiferromagnetic layer of a crystalline material formed over the second base layer, the antiferromagnetic layer having a crystal structure reflecting a crystal structure of the second base layer; a first ferromagnetic layer formed over the antiferromagnetic layer and having a magnetization direction defined by the antiferromagnetic layer; a nonmagnetic intermediate layer formed over the first ferromagnetic layer; a second ferromagnetic layer formed over the nonmagnetic intermediate layer having a magnetization direction changed by an external magnetic field; and a second electrode layer formed over the second ferromagnetic layer.
