Abstract
A magnetic cell includes a first magnetically fixed part including a laminated structure where a first ferromagnetic layer, a nonmagnetic layer and a second ferromagnetic layer are laminated, a second magnetically fixed part including a third ferromagnetic layer, a fourth ferromagnetic layer provided between the first and the second magnetically fixed parts, a first intermediate layer provided between the first magnetically fixed part and the fourth ferromagnetic layer, and a second intermediate layer provided between the second magnetically fixed part and the fourth ferromagnetic layer, a direction of magnetization of the fourth ferromagnetic layer being determined under an influence of spin-polarized electrons upon the fourth ferromagnetic layer by passing a current between the first and the second magnetically fixed parts.
