Abstract:
1. A magnetic memory element, comprising: a first stacked unit including a second stacked unit stacked with the first stacked unit in the stacking direction, the second stacked unit including a third ferromagnetic layer having a changeable direction of magnetization, a rotating magnetic field being generated by a precession of the magnetization of the third ferromagnetic layer when a current flows in the first stacked unit and the second stacked unit in one of a direction from the first stacked unit toward the second stacked unit and a direction from the second stacked unit toward the first stacked unit, the direction of the magnetization of the first portion and the direction of the magnetization of the second portion being oriented in a direction corresponding to an orientation of the current due to actions of the rotating magnetic field and spin-polarized electrons.
