Abstract
We carried out time-resolved magneto-photoluminescence experiments in dilut ed magnetic semiconducting Cd1-xMnxTe MBE grown epilayers to study the exci tonic localization mechanisms. We found that, for samples with a high nun-r adiative recombination rate, the luminescence intensity and the decay time decrease significantly under a magnetic field. This shows that the magnetic localization dominates over the non-magnetic localization when magnetic po larons are formed. (C) 2001 Published by Elsevier Science B.V.
