Abstract: A study has been made of the magnetic and electrical properties of oxygen-enriched La$_{1-x}$Ag$_x$MnO$_{3.1}$ manganites at 77 K $< T <$ 300 K. The samples have been produced by the sol-gel technique. The study has revealed an increase of the Curie temperature and a shift of the maximum in magnetoresistance toward high temperatures.
