Magnetization Switching of a Ferromagnetic Layer Using Spin-Orbit Torques in the Absence of any External Magnetic Field

Background SOT-MRAM is based on the reversible switching of the magnetization of one of two ferromagnetic layers in the magnetic tunnel junction (MTJ) due to the magnetic field created by an in-place current pulse. This causes the magnetization of the switchable ferromagnetic layer to precess toward an in-plane direction. After the current passes,...
