Popis:	Polycrystalline La 1− x Ag x MnO 3 perovskite compounds (with x =0.10–0.30) have been synthesised by both the conventional solid-state reaction and the sol–gel method. While all samples with Ag concentrations up to 0.20 consist of single-phase perovskites with rhombohedral structure, unreacted Ag was found in the samples with Ag concentrations of 0.22 and higher. Magnetic properties of the as-prepared materials have been investigated. The magneto-caloric effect in these compounds has been found to be considerably large and higher than that in other perovskite compounds in which La is substituted by divalent alkali-earth elements.
