Effect of Doping On Physico Chemical and Multiferroic Properties of Binary Compounds Batio3 Yfeo3

Abstract

Current work is divided into five major chapters, which starts with the literature review work on perovskite and multiferroic compounds especially on RFeO3 elements. Additionally various characterizations have been performed to prove its multiferroic property. In sight of the results we got, are also discussed in terms of application point of view especially in energy storage devices and in designing of MLCC. With the help of Solid State Reaction method, the parent compounds (BTO,YFO and BFO) are successfully synthesized and based on them, we proposed the binary compounds of xBTBF, xBTYF, BBTFx and BYTFx which are also synthesized by the help of Solid State Reaction method. newlineXRD results confirm the pure phase structure without much impurity and Compounds have either Hexagonal/tetragonal symmetry. We have also calculated crystallite size and amount of micro strain using Scherrer formula and W-H plot. SEM results confirm the good quality of the samples without much porosity. newlineOptical results obtained by FTIR confirm the existence of Ti-O/Fe-O/Ti-O + Fe-O in the prepared compounds. Results obtained using U. V. visible spectroscopy confirms the wide band gap semiconductor materials.Electrical results obtained by EIS show the compounds exhibit giant dielectric constant and low loss which make them usable for designing the MF/ME devices. Apart from this the conductivity results confirm the NTCR behavior of the compounds. The results of hysteresis obtained from P-E indicate the conventional nature of ferroelectric materials with some amount of leaky nature. Magnetic results confirm the paramagnetic nature of the compounds. newline newline
