1. A storage apparatus comprising:
a substrate; and
a storage element, the storage element comprising a storage layer, a magnetization layer and an intermediate layer, wherein
the magnetization layer includes a first ferromagnetic layer, a second ferromagnetic layer and a coupling layer between the first ferromagnetic layer and the second ferromagnetic layer,
the intermediate layer includes a nonmagnetic layer between the storage layer and the magnetization layer,
the magnetization layer includes the first ferromagnetic layer, the coupling layer and the second ferromagnetic layer laminated in order in a first direction,
the first ferromagnetic layer is configured to accommodate a first angle of magnetization in a cross-section perspective perpendicular to the first direction,
the second ferromagnetic layer is configured to accommodate a second angle of magnetization in the cross-section perspective,
the first and second ferromagnetic layers are arranged to accommodate the first angle being different from the second angle,
the first ferromagnetic layer is configured to accommodate a third angle of magnetization in a plan view perspective perpendicular to the cross-section perspective,
the second ferromagnetic layer is configured to accommodate a fourth angle of magnetization in the plan view perspective, and
the first and second ferromagnetic layers are arranged to accommodate the third angle being different from the fourth angle.
