A magnetic cell comprises: a first ferromagnetic layer whose magnetization is
substantially
fixed in a first direction; a second ferromagnetic layer whose magnetization is
substantially fixed in a second direction opposite to the first direction; a third
ferromagnetic layer provided between the first and the second ferromagnetic layers,
a direction of magnetization of the third ferromagnetic layer being variable; a
first intermediate layer provided between the first and the third ferromagnetic
layers; and a second intermediate layer provided between the second and the third
ferromagnetic layers. The direction of magnetization of the third ferromagnetic
layer can be determined under an influence of spin-polarized electrons upon the
third ferromagnetic layer by passing a current between the first and the second
ferromagnetic layers.
