Magnetic device and solid-state magnetic memory

Abstract

A magnetic device which has a layer having pores on a substrate and is to be used by applying electric current in the direction of depth of the pores comprises: a laminated structure in which a first ferromagnetic layer, a second ferromagnetic layer having a smaller coercive force than the first ferromagnetic layer and a non-magnetic layer are laminated within a part or all of the pores, wherein a hard layer having the first ferromagnetic layer, and a free ferromagnetic layer including the second ferromagnetic layer are laminated through the non-magnetic layer, and the hard layer further has a laminated structure in which a plurality of first ferromagnetic layers form antiferromagnetic coupling through the non-magnetic layer. A solid-state magnetic memory has the magnetic device.
