摘要：
Spin-polarized tunneling of excitons has been studied by the transient exciton luminescence in magnetic field in the double quantum well system. The double quantum well was composed of the wells of diluted magnetic semiconductor and nonmagnetic semiconductor. The spin-polarized excitons tunnel from the magnetic quantum well to the nonmagnetic quantum wells through the barrier, and their spins are conserved. The tunneling time of the exciton spins was determined from the circular polarization degree of the photoluminescence of the quantum well excitons. (C) 2001 Elsevier Science B.V. All rights reserved.
