Structural, micro-structural and physico-chemical studies of Polyvinylpyroledene (PVP) added Cobalt ferrite (CoFe2O4) nanoparticles

Abstract

To understand the structural and physico-chemical behavior of magnetic nanoparticle (CoFe2O4) is necessary for the selection of materials for various technological applications. The structural parameters derived from X-Ray diffraction (XRD) such as hopping length of site A (LA) and site B (LB), bond length between two A sites (dLA), two B sites (dLB), A and B (dLAB) and some related lengths. The micro-structural and magnetic studies from Fourier transform infrared spectroscopy (FTIR) and vibration sample magnetometer (VSM) analysis such as force constant, bond lengths between cation – anion (p, q, r, s) and cation - cation (b, c, d, e, f), and the angles between the bonds (θ1, θ2, θ3, θ4, θ5) values and trends were studied and it is merely suitable for 7.5 and 12.5 %. In addition some mechanical behavior obtained through their stiff constant C11 and C12 such as Young's modulus, bulk modulus, rigidity modulus and etc., The dielectric and electrochemical behavior of CoFe2O4 measured through AC conductivity (σAC), resistivity (ρAC) and electric modulus (M’, M’’ and M*) electrochemical parameters (V/I, impedance) through LCR and Cyclic voltameter measurements. The obtained results were interpreted and discussed extensively.
