Pure spin currents in magnetically ordered insulator/normal metal heterostructures
Pure spin currents in magnetically ordered insulator/normal metal heterostructures
Pure spin currents, i.e. the transport of angular momentum without an accompanying charge current, represent a new, promising avenue in modern spintronics from both a fundamental and an application point of view. Such pure spin currents can not only flow in electrical conductors via mobile charge carriers, but also in …
