A magnetic memory device includes a reference magnetic layer having a fixed magnetization direction, a tunnel barrier layer on the reference magnetic layer, a free layer having a variable magnetization direction on the tunnel barrier layer opposite the reference magnetic layer, and a magnetization reversal auxiliary layer on the free layer. The magnetization reversal auxiliary layer has a fixed magnetization direction that is substantially perpendicular to a plane along an interface between the tunnel barrier layer and the reference layer. The magnetization reversal auxiliary layer may be directly on the free layer, or an exchange coupling control layer may be provided between the magnetization reversal auxiliary layer and the free layer. |
