Critical behavior of the heat capacity of Ag-doped manganites

The critical behavior of the heat capacity of silver-doped manganites has been studied. The laws of variation in the universal critical parameters near the phase transition point have been established. It has been shown that the universality class of the critical behavior of the heat capacity for the La$_{1-x}$Ag$_y$MnO$_3$ $(y\le x)$ system does not depend on the silver concentration or the synthesis conditions.
