1. A storage element comprising:
a layer structure comprising layers arranged in a lamination direction, the layer structure including:
a storage layer having a direction of magnetization that is changeable according to information,
a magnetization fixed layer having a fixed direction of magnetization, the magnetization fixed layer including two ferromagnetic layers laminated interposing a coupling layer therebetween, the ferromagnetic layers being magnetically coupled interposing the coupling layer, the ferromagnetic layers having a direction of magnetization different from a direction perpendicular to a film surface of at least one of the ferromagnetic layers; and
an intermediate layer containing a nonmagnetic material disposed between the storage layer and the magnetization fixed layer, wherein
the layer structure is configured to accommodate recording via a change in the direction of magnetization of the storage layer.
