Optical studies of Mn2+ spin resonance in (Cd,Mn)Te quantum wells

We report optical investigations of Mn2+ spin resonance in (Cd,Mn)Te dilute magnetic semiconductor quantum wells. Raman scattering spin-flip measurements and optically detected magnetic resonance were performed on these samples. Both methods show features suggestive of Mn ion correlations-multiple Raman spin flips are observed in both Faraday and Voigt configurations. An unexpected multiplet of hypertine split lines is also observed in the magnetic resonance spectra. (C) 2003 Elsevier B.V. All rights reserved.
