Abstract:
1. A magnetic memory comprising a plurality of storage areas each of which has a magnetoresistive effect element, wherein the magnetoresistive effect element comprises: a first magnetic layer which contains a ferromagnetic material and a magnetization direction of which varies according to a density and a spin direction of an electric current flowing in a stack direction; a second magnetic layer which contains a ferromagnetic material, which is provided above one surface of the first magnetic layer, and a magnetization direction of which is fixed; a nonmagnetic layer which contains a nonmagnetic material and which is provided between the first magnetic layer and the second magnetic layer; a third magnetic layer which contains a ferromagnetic material, which is provided above another surface of the first magnetic layer, and a magnetization direction of which is fixed; and a first nonmagnetic conductive layer which contains a nonmagnetic and electrically conductive material and which is provided between the first magnetic layer and the third magnetic layer, and wherein an area of a cross section of the first magnetic layer perpendicular to the stack direction is not less than 0.001 μm
