Abstract
\(\hbox {Cd}_\mathrm{1-x}\hbox {Mn}_\mathrm{x}\hbox {Te}\) mixed crystals belong to a class of materials called “semimagnetic semiconductor” or diluted magnetic semiconductor with the addition of magnetic ions such as \(\hbox {Mn}^{2+}\) implemented into the crystal structure. The crystals under investigation were grown from the melt by the high-pressure high-temperature modified Bridgman method in the range of composition \(0<\mathrm{x}<0.7\). Thermal properties of these compounds have been investigated by means of photopyroelectric calorimetry in both back and front detection configurations. The values of the thermal diffusivity and thermal effusivity were derived from experimental data. The thermal conductivity of the specimens was calculated from the simple theoretical dependencies between thermal parameters. The influence of the Mn concentration on the thermal properties of \(\hbox {Cd}_\mathrm{1-x}\hbox {Mn}_\mathrm{x}\hbox {Te}\) crystals has been presented and discussed.
