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
