The correlation between Cd0.90-xMnxZn0.10Te (CMZT) melt state and structural properties of the crystals, grown by vertical Bridgman method, was investigated. The Cd0.9-xMnxZn0.1Te crystals with various Mn compositions (x = 0.1 and 0.2) were grown by a two-step method from high-purity elemental components. We have conducted a series of crystal growth runs with different degrees of melt superheating over the alloy's melting temperature. We obtained ingots with various crystalline structures and properties. It was concluded that the best crystals were grown from the melt with a thermal gradient of about 5 °C/cm during growth process. We have found that the band-gap increases (from 1.67 eV at x=0.1 to 1.79 eV at x=0.2) with Mn content.
