We have investigated the magnetic properties of single-crystal Cd1−xCrxTe and Zn1−xCrxTe samples. The magnetization is anisotropic (∼7% for Zn1−xCrxTe and ∼0.4% for Cd1−xCrxTe) with the (111) direction having the greatest value. We have found that the magnetic behavior in fields up to 6 T and temperatures between 1.5 and 324 K for both systems is well described by a theoretical model with crystal field, Jahn–Teller, spin-orbit, and spin-spin terms including ligand field corrections to the spin-orbit and spin-spin parameters. Good agreement was found between the experimental results and the theoretical calculations for a Jahn–Teller splitting of 370 and 320 cm−1 and effective spin-orbit parameters of −49.9 and −59.4 cm−1 for Cd1−xCrxTe and Zn1−xCrxTe, respectively. The key feature is an orbital singlet, S=2 ground state with a small splitting (1.5 K for Cd1−xCrxTe and 12.4 K for Zn1−xCrxTe) of the ms states. © 1996 American Institute of Physics.
