A current (white arrow) flowing through a tantalum film generates a current of spins (dark blue arrows) that impinges on the ferromagnetic cobalt iron boron layer and causes the magnetization (gold arrow) to charge directions (light blue arrow).

Theory of Spin-Orbit Torque

The working of countless electronic devices involves electric and magnetic effects interacting within nanostructured materials. In the phenomenon known as spin
