Abstract:
1. A magnetic memory element comprising: a stacked body, the stacked body including: a stray magnetic field Hs (Oe) from the first ferromagnetic layer, the second ferromagnetic layer, and the fourth ferromagnetic layer in a position of the third ferromagnetic layer, a magnetic anisotropy Ku (erg/cm the 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.
