Abstract

Nanocrystalline La0.7Sr0.2Ba0.1MnO3 (LSBMO) has been synthesized using two difference method, sol-gel and wet-mixing methods. Both samples were sintered at the same temperature of 900°C for 12 hours. Structural investigation using X-Ray Diffraction (XRD) shows that both samples crystallise in the same rhombohedral structure with R3c (167) space group. A slight difference on lattice parameters, unit cell volume and Mn-O bond length was observed. The crystallinity from the sol-gel method was better than that of from wet-mixing method. The average crystallite size was calculated by Scherer formula, namely 32.8568 nm for sol-gel method and 18.3777 nm for wet-mixing method. The electronic bandwidth which was calculated with theoretical approach reveal that the sol-gel method gives larger bandwidth than the wet-mixing method, which can affect the physical properties of the LSBMO.
