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.
