Abstract:Multiferroic materials with the compositional formulae Gd1-xHoxMn2O5 (x = 0, 0.1, 0.2, 0.3, and 0.4) were prepared by the conventional solid-state reaction method. The structural analysis has been carried out by X-ray diffraction technique which confirms the orthorhombic structure with the Pbam space group. The optical properties have been studied by UV Visible, FTIR, and Raman spectra. The energy gap that was calculated using UV visible absorption spectra shows that the material is semiconducting in nature. T… Show more
“…These shifting results from the crystal lattice expansion due to the doping of the higher ionic radius of Ho 3+ (0.901 Å) in the smaller ionic radius of Yb 3+ (0.86Å). 19 Rietveld refinement analysis.-To conduct a qualitative analysis of the samples, we employed Rietveld refinement using the Fullprof software, and the resultant plots are depicted in Fig. 2.…”
Using the traditional solid-state reaction approach, multiferroic ceramics with the compositional formula Yb1-xHoxMnO3, where x = 0 to 0.4 with 0.1 variation were synthesized. The structural and magnetic properties of the prepared poly-crystalline samples Yb1-xHoxMnO3 were investigated to show the effect of higher magnetic moment Ho3+ ion over the Yb ion. X-ray diffraction was used to analyse the compound’s crystal structure and confirm that they have a hexagonal single-phase structure with a P63cm space group. The presence of functional groups and their shifting to lower frequency regions were revealed by Fourier-transform infrared spectroscopy. UV-Vis absorbance spectra were used to calculate the energy gap values, and the resultant data shows a decrease in band gap values with an increase in Ho3+ doping. Crystal deformation with the doping of Ho3+ was observed using Raman spectra. Room-temperature magnetic studies were used to reveal the paramagnetic nature of the samples and the increase in magnetic parameters due to the doping of the higher magnetic moment Ho3+ ion.
