Description

The results on structural and magnetic properties of monocrystalline samples of the diluted magnetic semiconductor Hg1-xCrxSe with different concentrations of Cr ions (0< x<= 0,007 ) in the temperature range 50-300 K are presented. It is found, that the limit of existence of the homogeneous solid solution lies within the composition region x < 0.05. For samples with x >= 0,05 the drastic increase in magnetic susceptibility in the region of phase transition temperature is caused by both the phase transition to a spin glasslike state that takes place in all the samples investigated and the ferromagnetism developed due to ferromagnetic inclusions HgCr2Se4 and CrSe
