The temperature dependences of the heat capacity in the Pb₁-xMnxTe and Pb₁-xGexTe (x = 0-0.04) solid solutions based on PbTe were obtained in the temperature range of 100-670 K. Pronounced peaks were observed in the isotherms of the heat capacity in the vicinity of x ~ 0.01-0.015. The presence of th...
