Growth and characterization of Cd1−xMnxTe and MnTe crystals; contribution to the CdTe-MnTe pseudo-binary phase diagram determination

Large MnTe single crystals were grown by a modified Bridgman method and by THM. Large homogeneous Cd−1xMnxTe single crystals were grown by the Bridgman method with x = 0.01 to 0.75, and their electrical conductivity and Hall effect were measured. The CdTe-MnTe pseudo-binary phase diagram was studied by DTA and electron microprobe measurements. The solid solution range extends up to x = 0.77. The two phase field is remarkably narrow, accounting for the homogeneity of the Bridgman ingots.
