Abstract:
1. A magnetic memory element comprising: a stacked body, the stacked body including: a cross-sectional area of the third ferromagnetic layer being smaller than a cross-sectional area of the first stacked unit when cut along a plane perpendicular to the stacking direction, a direction of the magnetization of the second ferromagnetic layer being set to a direction in accordance with a direction of a current by causing an electron whose spin is polarized by passing the current through the stacked body along the stacking direction to act on the second ferromagnetic layer and by causing a rotating magnetic field generated from a precession of the magnetization of the third ferromagnetic layer to act on the second ferromagnetic layer, the current being flowed through the first stacked unit and the second stacked unit.
