Thermoelectric and magnetic properties of perovskite-type manganate phases synthesised by ultrasonic spray combustion (USC)

Abstract : Electron-doped manganate phases were synthesised by ultrasonic spray combustion (USC) to investigate the magnetic and transport properties related to their morphology. The nanocrystallite microstructure obtained from the USC synthesis is characterized by the presence of twinned domains coexisting with ordered crystalline material. Classical solid state reaction (SSR) methods were applied to compare their thermoelectric activities with the USC compounds. Magnetic properties and thermopower exhibit different features between USC and SSR phases at low temperatures. At high temperatures the USC compounds display higher power factor values compared to SSR phases due to low resistivity and large thermopower values.
