Current-Induced Polarization and the Spin Hall Effect at Room Temperature
Current-Induced Polarization and the Spin Hall Effect at Room Temperature
Electrically induced electron spin polarization is imaged in n-type ZnSe epilayers using Kerr rotation spectroscopy. Despite no evidence for an electrically induced internal magnetic field, current-induced in-plane spin polarization is observed with characteristic spin lifetimes that decrease with doping density. The spin Hall effect is also observed, indicated by an …
