Phys. 113, 054304 (2013); 10.1063/1.4790318 Spin-bias modulated Kondo effect in an interacting quantum dotWe propose a spin field effect transistor driven by spin biases which are externally generated in the source and drain electrodes. We employed the Keldysh non-equilibrium Green's function formalism to evaluate the charge and spin currents through the transistor, and verify the operation of the transistor as predicted by a semiclassical model. Our calculations show that in the "off" state, both the charge and spin currents are suppressed. In the "on" state, the device allows only the spin current to pass through but not charge current, thus potentially improving the energy efficiency of the device.

Waves of spin current in magnetized dielectrics

“…It is interesting to admit that in some devises the spincurrent exhibits the sine wave-like behavior [10]. New modification of spin-field effect transistors have been suggested (see for example [11], [12]), one of the spintronic devices utilize the electron's spin properties in addition to its charge properties. Effects in junction play key role in spintronic devises.…”
