Magnetization and spin-flip Raman scattering in Cd 1-xCr xSe and Cd 1-xV xSe
Spin-flip Raman scattering (SFRS) from donor-bound electrons in II-VI diluted magnetic semiconductors (DMSs) containing 3d transition-metal ions, e.g., Cd 1-xCr xSe and Cd 1-xV xSe, allows one to explore the exchange interaction between the conduction band or donor electrons with the 3d magnetic ions, which is the so-called s-d exchange interaction. The s-d exchange energy, being the SFRS Raman shift after subtracting the intrinsic Zeeman splitting characterized by g *=0.52 for CdSe, together with the magnetization measurements of those DMSs, allow one to deduce the s-d exchange constant N 0α. For Cd 1-xCr xSe and Cd 1-xV xSe, the N 0α values are 210±13 and 269±10 meV, respectively. © 2012 American Physical Society.
