| dc.description | Silver is known to be a highly mobile (low�soluble) component in Ag�doped perovskite mangan� ites and hence several non�perovskite phases can exist in silver doped manganite perovskites with most syn� thetic routes making its synthesis to be problematic. In search of soft synthesis route, the low temperature combustion synthesis and magneto�structural studies of polycrystalline La1 – xAgyMnO3 (y ≤ x) ceramic man� ganites using glycine as a fuel is reported. The sintered powders were characterized by X�Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X�ray (EDAX) analysis, Thermo Gravi�metric Analysis (TGA) and Vibrating Scanning Magnetometer (VSM) measurements. XRD patterns showed formation of mainly single rhombohedral perovskite phase for the La0.8Ag0.15MnO3 sample and an admixture of secondary phases with La0.8Ag0.1MnO3 and La0.8Ag0.2MnO3 samples. The distinct microstructure and higher magnetic properties observed for La0.8Ag0.15MnO3 sample compared to the other samples were dis�cussed based on the XRD results. | |
