The s,p-d exchange interaction in Zn1 − xCrxTe diluted magnetic semiconductors

W. Mac; A. Twardowski; M. Demianiuk

The reflectance in the free exciton range of Zn 1-x Cr x Te(x < 0.001) was measured in magnetic field up to 5 T and T = 2 K. The ferromagnetic type of exciton splitting was observed. Combining the optical data with the magnetization we estimated the p-d exchange constant N 0 β = + 3.6 ± 1.2 eV.
