Résumé
The s,p-d exchange interaction of hexagonal CdCrS is studied by means of Raman scattering and exciton magnetoreflectance. Analysis of Raman data yields s-d exchange parameter N-0 alpha = + 0.21 eV. Combining this parameter with the heavy-hole exciton splitting we evaluated the p-d exchange parameter N-0 beta = + 0.42 eV. The s,pd exchange parameters are used for interpretation of the exciton splitting in magnetic field for B parallel to c and B perpendicular to c. (C) 1998 Elsevier Science B.V. All rights reserved.
