This book presents the abstracts of the papers presented to the Online National Conference on Research and Developments in Material Processing, Modelling and Characterization 2020 (RDMPMC-2020) held on 26th and 27th August 2020 organized by the Department of Metallurgical and Materials Science in Association with the Department of Production and Industrial Engineering, National Institute of Technology Jamshedpur, Jharkhand, India.

A detailed study of electrical behavior of 95BiFeO 3 -5BaTiO 3 (95BFO-5BT) ceramics through comprehensive analysis of temperature and frequency dependent dielectric behavior, ac impedance and magnetodielectric (MD) properties is reported here. Addition of insulating BaTiO 3 into BiFeO 3 have exhibited enhanced dielectric and ferromagnetic responses. The remnant polarization (P r ) was found to be 6 lC/cm 2 , while the dielectric constant was found to be very high (e 0 r C 10 2 , for T C 140°C). Along with strong conductivity contribution to e 0 r , spectroscopic plots of e 0 r revealed the MaxwellWagner type relaxation in the sample, which ultimately could have led to an apparent high e 0 r in 95BFO-5BT ceramics. Origin of such a high e 0 r in BFO-BT was further investigated using impedance spectroscopy. MD studies revealed the magneto-electric coupling in the ceramics. The MD studies along with anomaly in dielectric data near antiferromagnetic ordering temperature (T N = 170°C) of BFO suggests the magnetic bearing on the electrical properties of 95BFO-5BT ceramics.
