Abstract
The diluted magnetic (‘‘semimagnetic’’) semiconductor Cd1–xMnxTe reveals intriguing spin glass properties. In this paper, the results of neutron scattering studies of Cd1–xMnxTe are presented. The low‐temperature spin correlations have been studied for several single crystal samples in the composition range 0.60<x0.35Mn0.65Te have also been carried out, revealing broad magnon‐like maxima in the scattered spectra. Computer calculations of the elastic neutron scattering cross section and some other quantities characterizing the system have been performed using the Monte Carlo modelling method, and the accepted data for exchange interactions in Cd1–xMnxTe. The results of these calculations are discussed in the light of the experimental results.
