Abstract: The results of the influence of the isotopic substitution of oxygen $^{16}$O $\to$ $^{18}$O on the susceptibility, electrical resistance, heat capacity, and the magnetocaloric effect in univalently doped manganite La$_{0.8}$Ag$_{0.1}$MnO$_3$ are presented. It has been shown that the substitution of $^{16}$O by a heavier isotope $^{18}$O leads to a shift in $T_C$ and affects all the measured coefficients. This result indicates the necessity of accounting the lattice dynamics when explaining the mechanism of colossal magnetoresistance in manganites.
