Synthesis of ytterbium-doped neodymium ferrite oxide using solid-state reaction method and its characterization

Abstract

The Yb doped NdFeO 3 using a solid-state reaction method has successfully synthesized. In this paper, Nd 1-x Yb x FeO 3 samples were synthesized by varying the molar ratio of Yb at × = 0.01, x = 0.05, and × = 0.10 using solid-state reaction with two routes of heat treatment processes. Results of X-ray diffraction show that all samples have an orthorhombic structure with two phases: NdFeO 3 as a major phase and Nd 2 O 3 as a minor phase. FWHM value for a maximum peak is 0.2°, so the estimated crystal size is 40 nm, with the dominant peak corresponding to hkl (1 2 1). Morphology properties used SEM Image shows grain size of al sample estimated at 0.4 μm. The presence of Yb is quantitatively confirmed based on the EDS result.
