Abstract
A magnetoresistive random-access memory (MRAM) is disclosed. The MRAM device includes a perpendicular magnetic tunnel junction device having a reference layer, a free layer, and a precessional spin current magnetic layer. The precessional spin current magnetic layer has a central axis that is offset from a central axis of the free layer. The device is designed to provide control over the injection of stray fields and the electronic coupling between the precessional spin current magnetic layer and the free layer. Switching speed, switching current, and thermal barrier height for the device can be adjusted. The off-center design may be used to adjust the location of the stray-field injection in the free layer.
