Abstract:
A memory element has a layered configuration, including a memory layer in which a magnetization direction is changed corresponding to information; the magnetization direction being changed by applying a current in a lamination direction of the layered configuration to record the information in the memory layer, a magnetization-fixed layer in which a magnetization direction is fixed, an intermediate layer that is formed of a non-magnetic material and is provided between the memory layer and the magnetization-fixed layer, and a perpendicular magnetic anisotropy inducing layer, the memory layer including a first ferromagnetic layer, a first bonding layer, a second ferromagnetic layer, a second bonding layer and a third ferromagnetic layer laminated in the stated order.
