Abstract

Spin-flip scattering of oriented carriers between Zeeman-split quantum-confined states is observed directly by femtosecond-resolved photoluminescence spectroscopy in magnetically coupled double quantum wells. Polarization measurements reveal that the spin dynamics are determined by the initial carrier energy and spin orientation with respect to the Zeeman separation of the levels. Studies as a function of applied field and barrier thickness show that spin equilibration is remarkably sensitive to the magnetic environment.
