Using high temperature solid state reaction technique ceramic composites (1-x)BiFeO3 - xBa5TbTi3V7O30 having different x values are prepared. Basic crystal qualities are studied using XRD which shows that there’s a formation of BiFeO3 and Ba5TbTi3V7O30 phases. There observed change in the basic structure as x changes and is most distorted for x = 0.5. From SEM study, it is found that the grain size is minimum for pure ferroelectric sample and maximum for x = 0.5. Dielectric constant ( r) and Dielectric loss (tanδ) has been measured at wide temperature range (RT- 673 K). With increase in the value of x, there is also increase in Dielectric constant ( r) and is maximum for x = 1. Magnetic measurement is done at low temperature by VSM which shows that the magnetization is maximum for x = 0.3. HIGHLIGHTS One of the major limitations in the utility of multiferroic materials is that it has low dielectric value and low magnetization value A ferroelectric material is doped with the multiferroic materials and the electrical and magnetic properties are being analyzed There is an enhancement in the ferroelectric and ferromagnetic properties of the doped materials GRAPHICAL ABSTRACT
