Synthesis and Characterization of La0.8Sr0.1Ag0.1MnO3 Nano Perovskite Compound

Nano-crystalline perovskite of the general formula La0.8Sr0.1Ag0.1MnO3 was synthesized using the Pechini sol-gel method. Variation of the gel pH was done during synthesis process to control the aggregation of particles and their crystal structural. The synthesized nanoparticles were characterized using X-ray analysis (XRD), High Resolution Transmission Electron Microscope (HR-TEM) andThermal analyses(TGA/DTA). XRD confirms the formation of the pure phase perovskite inrhombohedral structure with R-3c space group and with crystallite size about 28 nm.The HR-TEM analysis further confirms the nanosize of the particles, which lie in the range of 35-40 nm. The magnetic hysteresis measurements were performed using a vibrating sample magnetometer (VSM).Magnetic parameters such as saturation magnetization, remanent magnetization, and coercivity were obtained. Based on the value of coercivity, this sample is good suited for data storage devices.
