Magnetic interactions and dielectric behaviour of cobalt ferrite and barium titanate multiferroics nanocomposites

Abstract Multiferroics materials have been used widely in various fields such as ceramic supercapacitors, active and multifunctional devices due to their high relative permittivity with magnetic and ferroelectric behavior even at room temperature. The composites of cobalt ferrite, barium titanate have been synthesized through co precipitation technique and sintered at very high temperature1273K. The existence of titanate single phase and cobalt ferrite structural analysis carried out through ‘X’ Ray diffraction analysis. From the AC analysis the role of phase, dielectric constant, loss tangent and conductivity was also studied. AC conductivity variation was very low at lower frequencies and increases with frequency. Magnetization measurements were carried out at room temperature shows soft ferromagnetic property is 2.8089 emu/g.
