Synthesis And Characterization Of Pb Fe0 5Nb0 5 O3 Based Multiferroic Solid Solution

Abstract

newline In the field of development and research, there is currently significant interest in investigating and exploring a unique class of materials known as multiferroics. These materials exhibit both ferroelectricity and magnetism simultaneously within a single- phase compound. Although complicated, the idea of multiferroics has increased the demand for synthesized materials with a thorough understanding of its interesting physics for a variety of technical and industrial applications. The scientific community has paid a lot of attention to Pb(Fe0.5Nb0.5)O3 (PFN) over the past decade because of its excellent multiferroic characteristics and potential for use in innovative devices. newlineThis work mainly focussed on the synthesis and characterization of two material systems: newline1. (1-x)Pb(Fe0.5Nb0.5)O3 xBaTiO3 solid solution, with varying compositions of x=0, 0.025, 0.05, and 0.1, denoted as PFN-BT. 2. Pb1-xNdx(Fe0.5Nb0.5)1-x/4O3 solid solution, with varying compositions of x=0, 0.02, 0.04, 0.08, and 0.1, denoted as PNFN. newlineThe substitution of BaTiO3 (BT) and Nd has been done in order to improve the structural, dielectric, impedance, ferroelectric as well as ferromagnetic properties of the as - synthesized compound for their respective suitable electronic applications. Fabrication of the selected series of materials was carried out through a single-step solid state reaction (SSR) method. Formation of pure phase materials was revealed through the analysis of X-ray diffraction (XRD) data. Detailed examination of the structure shows that all the samples exhibit monoclinic crystal system with Cm space group. The substitution has a marked effect on unit cell volume and lattice parameters. The densely packed grains and homogeneous distribution of grains all over the sample surface has been confirmed from the field emission scanning electron micrograph (FESEM). The comprehensive analysis of electrical parameters i.e. conductivity, impedance, and modulus of the selected series of materials were performed over a broad fre
