Abstract
A magnetic tunnel junction (MTJ) device includes a reference layer having a surface, a tunnel insulating layer formed over the surface of the reference layer, a free layer formed over the tunnel insulating layer, and a magnetic field providing layer formed over the free layer. A magnetization direction in each of the reference layer and the free layer is substantially perpendicular to the surface. The magnetic field providing layer is configured to provide a lateral magnetic field in the free layer, the lateral magnetic field being substantially parallel to the surface.
