- Electron probe microanalysis and X-ray diffraction studies have been performed on samples of ternary Cd$\text{}_{1-x}$Mg$\text{}_{x}$Te (0.05 ≤ x ≤ 0.09) and quaternary Cd$\text{}_{1-x-y}$Mg$\text{}_{x}$Mn$\text{}_{y}$Te (0.025 ≤ x ≤ 0.4; 0.025 ≤ y ≤ 0.7) alloys. The investigated samples were cut from 24 different ingots grown by Bridgman method. Microprobe examinations have revealed significant differences between actual and nominal content of Mg along the longitudinal direction for both ternary and quaternary ingots. In contrast to Mg, for most Cd$\text{}_{1-x-y}$Mg$\text{}_{x}$Mn$\text{}_{y}$Te samples the actual Mn content was within ±5% of nominal content. The lattice constants have been determined by X-ray powder diffraction method. Whereas Cd$\text{}_{1-x-y}$Mg$\text{}_{x}$Mn$\text{}_{y}$Te samples exhibit only zinc blende crystal structure for the entire region of x and y investigated, the Cd$\text{}_{1-x}$Mg$\text{}_{x}$Te alloy has two different structures depending on Mg content; a zinc blende structure below x = 0.5 and a wurtzite structure above it. In both alloys the lattice constant decreases with increasing Mg content.
