MAGNETIC-SUSCEPTIBILITY OF HGTE[MN,FE,CR]

The results of the investigations of magnetic susceptibility (chi) 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 (chi Mn)(T) and (chi Fe)(T) in HgTe(Mn, Fe) are described by Cur ie law and for N-3d > 10(21) cm(-3) - by Curie-Weiss law with negative value of theta(p) characterizing the antiferromagnetic interaction be tween magnetic ions. Thermal treatment of HgTe(Fe) samples in Hg vapou r at T = 500 K in contrast to HgTe(Mn) leads to tile redistribution of magnetic component only in these samples. A special behaviour of (chi )(T) in HgTe(Cr) samples was revealed which is different from (chi)(T) in HgTe(Mn, Fe).
