Abstract

The effect of copper substitution on the structure of La_0.7S_0.25Nd_0.05Mn_1-xCu_xO₃(x = 0, 0.03, 0.05, and 0.07) has been studied by using X-ray diffraction (XRD). The samples were successfully synthesized by using citrate-nitrate sol-gel method. Rietveld refinement analysis showed that all samples crystallized in rhombohedral system with R3c space group without any detectable trace of impurities. Further analysis on the crystal structural of the samples revealed that copper substitution decreases the average Mn-O-Mn bond angle (<Mn-O-Mn>) and increases the Mn-O bond length (d_<Mn-O<). Scherrer equation showed the samples are in nanocrystalline. X-ray fluorescence (XRF) results indicate that copper has successfully substituted the manganese ion.
