Nuclear electric resonance and orientation of carrier spins by an electric field
Aronov A. G. , Lyanda-Geller Yu. B.
An orientation of carrier spins arises during the flow of a current through a crystal, in which there is a spin splitting of bands which is linear in the momentum. This orientation effect can be detected from the nuclear resonance which is induced by an alternating electric field and also from the polarization of luminescence spectra.
