The temperature dependence of the band gap for HgCdTe and HgCdMnTe has been experimentally investigated in the temperature range of 7-250 K. The distinct nonlinear dependence has been observed in the low temperature range. It was shown that the lattice dilatation contribution calculated for HgCdTe is a significant part (about 30%) of the total temperature shift of the energy gap.
