Abstract
A magnetic unit includes: a magnetic pinned layer, a first function body, and a second function body. The magnetic pinned layer is provided that a magnetization direction is pinned. The first function body is provided in contact with the magnetic pinned layer and performs a function with the magnetic pinned layer. The second function body is provided in contact with the magnetic pinned layer. The second function body is any of a nonmagnetic conductor, a nonmagnetic insulator, and a function body. The magnetic pinned layer includes: a plurality of magnetic substance layers, and a nonmagnetic conductive layer provided between the plurality of magnetic substance layers. The nonmagnetic conductive layer ferromagnetically or antiferromagnetically couples magnetic substance layers on both sides. A total amount of magnetizations of the plurality of magnetic substance layers is approximately zero. Among the plurality of magnetic substance layers, a magnitude of an anisotropic magnetic field of a group of magnetic substance layers directed toward a first direction is different from that of a group of magnetic substance layers directed toward a second direction.
