Abstract:
1. A magnetic memory device comprising: a first write wiring which runs in a first direction; a second write wiring which runs in a second direction different from the first direction; and a magnetoresistive element which is arranged at an intersection between the first write wiring and the second write wiring, has a fixed layer, a recording layer, and a magnetoresistive layer sandwiched between the fixed layer and the recording layer, and has an axis of easy magnetization obliquely with respect to the first direction and second direction, the recording layer including a first ferromagnetic layer, a second ferromagnetic layer, and a first nonmagnetic layer sandwiched between the first ferromagnetic layer and the second ferromagnetic layer, in which first magnetization of the first ferromagnetic layer and second magnetization of the second ferromagnetic layer are ferromagnetically coupled, and a ferro-coupling constant C of a ferromagnetic coupling is 0.0001 erg/cm
