Injection of Spin-Polarized Carriers from a ZnMnSe/CdSe Semimagnetic Superlattice into a Non-Magnetic ZnCdSe Quantum Well

Abstract

We report on magneto-optical studies of spin injection from a ZnMnSe/CdSe semimag- netic short-period superlattice (SL) to a non-magnetic ZnCdSe quantum well (QW). The carriers are photo-generated in the semimagnetic SL spin polarized via the effect of giant Zeeman splitting and then injected into the non-magnetic QW through a tunneling mechanism. Near 25% injection efficiency has been demonstrated at the magnetic field of 0.8 T and low temperature (1.8 K).
