The results of the investigations of magnetic susceptibility (χ) of HgTe⟨Mn,Fe,Cr⟩ with N3d < 1021 cm-3 in temperature range of 80-290 K and for magnetic fields of 0.4-9 kOe are presented. It was shown that χMn(T) and χFe(T) in HgTe⟨Mn,Fe⟩ are described by Curie law and for Ν3d > 1021 cm-3 - by Curie-Weiss law with negative value of θp, characterizing the antiferromagnetic interaction between magnetic ions. Thermal treatment of HgTe⟨Fe⟩ samples in Hg vapour at Τ = 500 K in contrast to HgTe⟨Mn⟩ leads to the redistribution of magnetic component only in these samples. A special behaviour of χ(T) in HgTe⟨Cr⟩ samples was revealed which is different from x(T) in HgTe⟨Mn,Fe⟩. |
