Abstract
Ultrafast spin dynamics in diluted magnetic semiconductor heterostruct ures are probed to observe the effects of dimensionality and quantum c onfinement on spin scattering. Two novel structures, the spin superlat tice and the magnetically-coupled double quantum well, exhibit unusual spin behavior. These experiments resolve energy-dependent electronic and magnetic interactions on a femtosecond time scale in quantum geome tries.
