It has been reported that spins are formed inside a nanomagnet if electric current is applied to the nanomagnet. There have been no studies on the physical results of these spins. Researchers in South Korea have established a theoretical system by developing a spin diffusion equation that describes the spin conductance in magnetic materials. They discovered that when the spins formed by electric current is emitted to the outside, only the sign is opposite to that of the spins injected from the outside, and the effects are the same. Therefore, the directions of the N pole and S pole can be controlled by the nanomagnet itself without external spin injection, and the power consumption can be reduced by up to ~60% compared to that of conventional spin devices. The study provides an academic basis for spin conductance in magnetic materials…read more. TECHNICAL ARTICLE
