Ferromagnetic laminated film, spin current magnetization rotary element, magnetoresistive effect element and magnetic memory

摘要

The ferromagnetic layer isA plurality of first magnetic layers andAt least one second magnetic layer andComprising at least one first non-magnetic layer;The first magnetic layer is alternately laminated with the second magnetic layer or the first nonmagnetic layer;The material constituting the first magnetic layer is different from the material constituting the second magnetic layerThe first magnetic layer, the first non-magnetic layer and the second magnetic layerA material combination between the first magnetic layer and the first nonmagnetic layer is an interfacial magnetic anisotropy.It is a material combination in which interfacial magnetic anisotropy occurs between the first magnetic layer and the second magnetic layer.
