Abstract

Embodiments herein relate to magnetically doping a spin orbit torque electrode (SOT) in a magnetic random access memory apparatus. In particular, the apparatus may include a free layer of a magnetic tunnel junction (MTJ) coupled to a SOT electrode that is magnetically doped to apply an effective magnetic field on the free layer, where the free layer has a magnetic polarization in a first direction and where current flowing through the magnetically doped SOT electrode is to cause the magnetic polarization of the free layer to change to a second direction that is substantially opposite to the first direction.
