Spin pumping: An Introductory Overview
With STT, we have seen that a current can move magnetization, but the reciprocal effect is also possible, namely the generation of a spin current by magnetization motion. This phenomenon is called spin pumping and it is essential for developing spintronic devices, which utilize the spin of electrons rather than ...
Spin-Transfer Torque: An Introductory Overview
Next to the charge, electrons also posses spins. In normal electronic circuits it is of (hardly) no use, as they are orientated randomly in non-ferromagnetic materials. However, when we integrate ferromagnetic components into these devices, the itinerant electrons can become partially spin polarized, with their spins taking on a more ...
