Resumo

Polycrystalline Cd1–хZnхTe (x = 0.005, 0.03, 0.05) ingots have been obtained by the modified Obreimov–Shubnikov method. The selected single-crystal blocks are studied applying the X-ray diffraction analysis, measurement of electrical characteristics, and magnetometry. The concentration dependence of changes in the magnetic and electrical properties of crystals is investiga11ted. It is established that at Zn concentrations of x = 0.03 and 0.05 ferromagnetic ordering is observed in clusters (inclusions) containing iron and/or nickel at 2 K, which is not observed for Cd1–хZnхTe (x = 0.005) samples.
