Functional Ceramic Ferroelectromagnetic Materials in Single Phase Solid-Solutions

Abstract

1. Perform a detailed study on magneto-dielectric effect in the ferroelectric ferromagnet (FEM) ternary oxide solid solutions like Bi(TM)O3-(La1-xREx)0.67(Ba/Ca)0.33MnO3-BTiO3,where TM=transition metal, initially Fe, RE=Rare Earth and B= Ba, Pb. 2. To find suitable composition such that the ferroelectric and ferromagnetic properties are observable at or near room temperature. 3. To decrease the difference between the ferroelectric (Tfe) and ferromagnetic (TN or Tc) transition temperatures by modifying BiFeO3, and 4. To enhance ferroelectromagnetic behavior in the modified BiFeO3. The details of the results and discussion are presented in the final report.
