Nuclear spin effect in metallic spin valve
arXiv:cond-mat/0605703 · doi:10.1103/PhysRevLett.97.146602
Abstract
We study electronic transport through a ferromagnet normal-metal ferromagnet system and we investigate the effect of hyperfine interaction between electrons and nuclei in the normal-metal part. A switching of the magnetization directions of the ferromagnets causes nuclear spins to precess. We show that the effect of this precession on the current through the system is large enough to be observed in experiment.
