Direct Demonstration of Decoupling of Spin and Charge Currents in Nanostructures
Direct Demonstration of Decoupling of Spin and Charge Currents in Nanostructures
The notion of decoupling of spin and charge currents is one of the basic principles underlying the rapidly expanding field of spintronics. However, no direct demonstration of the phenomenon exists. We report a novel measurement in which a nonequilibrium spin population is created by a pointlike injection of current from …
