Abstract

Crystalline structure of La0.7Sr0.25Nd0.05MnO3 (LSMNO) manganite have been investigated in order to study the effect of various sintering temperature. A series of LSMNO samples were prepared by citrate-nitrate sol-gel method followed by various sintering temperature at 700 oC, 800 oC, and 900 oC. The crystalline structure of the samples was investigated by using X-ray diffractometer (XRD). The XRD patterns obtained were then analyzed by means of Rietveld refinement method. According to the XRD results there was no secondary phase found in all samples. Furthermore, refinement process show that all samples crystallize with rhombohedral symmetry within the space group of R3 ̅c regardless the applied various sintering temperature. Further crystallographic study reveals that average Mn-O bond length increases meanwhile average Mn-O-Mn bond length decreases as sintering temperature were increased. To confirm chemical composition of LSMNO samples, we use X-ray fluorescence (XRF). XRF result reveal that all samples support stoichiometry design.
