Effect of Ag substitution on the structural and magnetic properties of Sm0.55Sr0.45MnO3 (x = 0, 0.15) system

We report the structural and magnetic properties of Ag substituted Sm0.55Sr0.45MnO3 (x = 0, 0.15) synthesized via solid state reaction method. The XRD patterns using Full Prof Rietveld analysis shows that the samples have single phase nature without any detectable impurity. SEM results shows that the grain size increases upto sharper instant. The magnetic studies reveals Neil temperature (TN) and Curie Temperature (Tc) get decreased with the lowering of temperature. The hysteresis loss which is dominant in pure sample disappears in Ag doped one. This shows that Ag helps in achieving the homogeneity thereby decreasing the disorder.
