Prof. Salahuddin: Switching of Perpendicularly Polarized Nanomagnets with Spin Orbit Torque Without an External Magnetic Field by Engineering a Tilted Anisotropy

When a spin orbit torque is applied to a magnet with perpendicular anisotropy, the induced spin accumulation is completely symmetric with respect to the magnetization. As a result, a deterministic switching cannot be achieved unless an external magnetic field is applied to break the symmetry… Read more>> http://www.pnas.org/content/early/2015/07/29/1507474112.abstract
