Claim:
1. A magnetic memory comprising: a multilayer structure including a first nonmagnetic layer, a first ferromagnetic layer, a second ferromagnetic layer between the first nonmagnetic layer and the first ferromagnetic layer, and a second nonmagnetic layer between the first ferromagnetic and the second ferromagnetic layer, the second ferromagnetic layer including an oxide magnetic material; a first wiring line electrically connected to the first nonmagnetic layer; a second wiring line electrically connected to the first ferromagnetic layer; and a voltage applying circuit electrically connected between the first wiring line and the second wiring line to apply a first voltage between the first nonmagnetic layer and the first ferromagnetic layer during a write operation, a magnetization direction of the second ferromagnetic layer being switchable by applying the first voltage.
