Abstract

We report on the effect of Pr doping on structural, magnetic and magnetocaloric properties in (La1-xPrx)(0.85)Ag0.15MnO3 (0.0 <= x <= 0.5) compounds. The main crystal structure has been studied by performing X-ray diffraction method and structural analysis based on Rietveld method where it is found that although samples at low concentration level (x <= 0.2) have rhombohedral phase
