A study on structural and physical properties of NdMnO3and Nd0.7Ag0.3MnO3

Abstract

Pure and Ag-doped NdMnO3 were synthesized using the conventional solid-state reaction route to investigate the structural and physical properties of both samples. The crystal structural of both samples were determined using X-ray diffraction (XRD) and Fourier Transform Infrared spectroscopy (FTIR). The Rietveld refinement showed that the compounds crystallized in orthorhombic structure, with the decrease in volume from 233.50 (x = 0) to 231.03 (x = 0.3) with the increase of lattice parameter b from 5.56 to 5.69, respectively. FTIR spectra showed that absorption bands were located within the range of 580 - 600 cm -1, which corresponded to the Mn-O stretching vibration.
