Dynamic spin-charge coupling: ac spin Hall magnetoresistance in nonmagnetic conductors

The dynamic coupling between spin and charge currents in nonmagnetic conductors is considered. As a consequence of this coupling, the spin dynamics is directly reflected in the electrical impedance of the sample, with a relevant frequency scale defined by spin relaxation and spin diffusion. This all...

Beschreibung
Zusammenfassung:The dynamic coupling between spin and charge currents in nonmagnetic conductors is considered. As a consequence of this coupling, the spin dynamics is directly reflected in the electrical impedance of the sample, with a relevant frequency scale defined by spin relaxation and spin diffusion. This allows the observation of the electron spin resonance by purely electrical measurements.
