Effect of Bi Substitution on Structural and AC Magnetic Susceptibility Properties of Nd1−xBixMnO3

Abstract

This study synthesizes the neodymium-based manganites with Bi doping, Nd1−xBixMnO3 (x = 0, 0.25 and 0.50) using the solid-state reaction route. The crystal structural, morphological and magnetic properties were determined using X-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) and AC magnetic susceptibility. The Rietveld refinement confirmed that the compounds were in the single-phase orthorhombic structure of the NdMnO3 with Pbnm space group and lattice parameter b increased with doping from 5.5571 (x = 0) to 5.6787 (x = 0.5). FTIR spectra showed that absorption bands were located within the range of 550–600 cm−1, which corresponded to the Mn–O stretching vibration. FESEM exhibited homogenous compound. The AC magnetic susceptibility measurement studies showed a strong antiferromagnetic (AFM) to paramagnetic (PM) transition existed at 76 K, 77 K and 67 K for samples (x = 0, 0.25 and 0.50), respectively.

“…These articles were related to the determination of the effects of the addition of various nanoparticles (GaF 3 , ZnF 2 , Zn(BF 4 ) 2 and Ga 2 O 3 ) on the activity of CsF-RbF-AlF 3 flux and the mechanical behavior of Al/steel brazed joints. Among others, it was shown that the CsF-RbF-AlF 3 flux doped with GaF 3 obtained the maximum spreading area, both on 6061 aluminum alloy and Q235 low-carbon steel, and reached the highest shear strength of 126 MPa.Nur Baizura Mohamed et al [6] have studied the effect of Bi substitution on the structural and magnetic susceptibility properties of Nd 1−x Bi x MnO 3 . The XRD analysis and Rietveld refinement show the pattern corresponding to the perovskite-type NdMnO 3 , which crystallizes in the orthorhombic system with main peak at (121) hkl plane with the Pbnm space group.…”
