Abstract

Strontium-doped lanthanum manganite (La0.9Sr0.1MnO3-δ) were synthesized by spray pyrolysis technique in the thin film form on alumina substrate. The La0.9Sr0.1MnO3-δ (LSM) thin films were sintered in the step of 150 oC from 600oC to 900oC. X-ray diffraction study confirmed phase formation of LSM and Infrared spectroscopy confirmed perovskite structure. Morphology of LSM has been studied by using Scanning electron microscopy and Atomic force microscopy, shown porosity within homogeneous grain structure. TGA/DSC and DTA study exhibits stable crystallization after 700oC. Dielectric study shows mixed electrica
