Structure identification of Nd1-xYbxFeO3 (x = 0.01, 0.05 and 0.10) using Rietveld refinement method

Abstract The XRD data of NdFeO3 doped Yb has been successfully analyzed by Rietveld refinement method. The Nd1-xYbxFeO3 crystallographic data used base on X-ray diffraction results to obtain their crystal structure and phase. The Rietveld refinement method in Rietica software was used to analyze the lattice parameters of the samples. The result of X-ray diffraction shows that the presence of Yb did not affect the crystal structure of NdFeO3. The Rietveld refinement process shows that all samples have a good refinement indicating by the value of χ2 ranging from 1.2 to 1.4 and the good visualization of the graph between experimental and calculation patterns. Further analyses of lattice parameter results then explained in this paper.
