| Abstract: | In this thesis, the new powder material La1.4Sr1.66Mn2O7 was synthesized by a sol - gel method We studied that the electrical conductivity of samples was found to obey the small polaron hopping mechanism and increase obviously in the temperature of 400 -900℃; XRD measurements, structure of the samples belongs to the etragonal structure, and indicates that LSMO has a good chemical compatibility with the 8YSZ electrolyte. |
