Abstract / Description:An investigation of resistively detected electron paramagnetic
resonance (EPR) of Mn2+ ions imbedded in CdMnTe modulation-
doped quantum well structure reveals the strong influence of
the 2D-free carriers on the resonance position (Knight shift).
The EPR experiments have been performed at low fields and for v
= 3 quantum Hall state. The observed Knight shift at v = 3 is
huge and cannot be explained by standard models (mean field
approach) of mutual interaction between spins of band electrons
and magnetic moments in diluted magnetic semiconductors. (C)
