Abstract

This paper reports the synthesis and characterization of two new complex precursors of LaMnO3 perovskite oxide doped with Strontium. The complex precursors have been prepared in La (CH3COO)3 – Mn (CH3COO)2 – AOH – DMF systems (where AOH = dimethylaminoethanol or 2[(diethylamin) methyl]-6-ethylpheno; DMF - dimethylformamide). Electronic and FT-IR spectra, TG / DTA analysis as well as molar conductivity measurements, have been used. According to the XRD patterns, LaMnO3 obtained by the calcinations of the heterodinuclear complex precursors are single phase with rhombohedral perovskite type structure. The magnetic properties of the powders and thin films of perovskite manganite, obtained by annealing at different temperatures of Sr doped Lanthanum Manganite precursors, have been determined by Vibrating Sample Magnetometry and correlated with microstructural properties of thin films of Sr doped Lanthanum Manganite..
