Abstract
Spin-flip scattering of oriented carriers between Zeeman-split quantum -confined states is observed directly by femtosecond-resolved photolum inescence spectroscopy in magnetically coupled double quantum wells. P olarization 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 fie ld and barrier thickness show that spin equilibration is remarkably se nsitive to the magnetic environment.
