Abstract: The temperature dependences of the velocity of longitudinal sound, internal friction, and magnetization of the single crystal with the nominal composition La$_{0.6}$Pr$_{0.1}$Ca$_{0.3}$MnO$_3$ have been measured. It has been found that the substitution of praseodymium for lanthanum in La$_{0.7}$Ca$_{0.3}$MnO$_3$ leads to a decrease in the velocity of sound and to an increase in the spontaneous magnetization. The method of determining the Curie temperature distribution function during a first-order transition has been proposed. It has been shown that, in the crystal under study, this function is asymmetric.
