Zusammenfassung:Results of the experimental studies of resistivity, specific heat, and magnetocaloric effect in lanthanum deficient manganite of La0.8Ag0.1MnO3 are presented. The influence of isotopic substitution of oxygen 16О arrow right 18О on the resistivity, specific heat, and magnetocaloric effect in La0.8Ag0.1MnO3 is estimated. The magnetocaloric effect has been studied by two different methods, which agree well enough. The entropy change as a result of the magnetocaloric effect varies between 2 and 4.1 J/kg K in the magnetic field of 26 kOe in the study samples.
