The results of the investigations of magnetic susceptibility (χ) of HgTe⟨Mn,Fe,Cr⟩ with N_{3d} < 10^{21} cm^{-3} in temperature range of 80-290 K and for magnetic fields of 0.4-9 kOe are presented. It was shown that χ_{Mn}(T) and χ_{Fe}(T) in HgTe⟨Mn,Fe⟩ are described by Curie law and for Ν_{3d} > 10^{21} cm^{-3} - by Curie-Weiss law with negative value of θ_{p}, 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⟩.
