Ce-doped polycrystalline 0.7BiFeO3-0.3(BaTi1-xCexO3) (x=0.00-0.07) ceramics were synthesized via solid-state method. XRD confirmed a rhombohedral perovskite structure, with lattice parameters and Fe-O bonds showing distortions upon Ce addition. FE-SEM revealed homogeneous grain distribution with well-defined boundaries, indicating densification. Magnetic measurements using VSM showed variations in the saturation magnetization and coercivity with Ce ions. The highest magnetization occurred at x=0.03 and decreased at higher concentrations due to Fe3+ superexchange interaction dilution.
Dielectric measurements showed Curie temperature decreased and then stabilized at higher Ce concentrations. Polarization-electric field loops indicated a transition from ferroelectric to relaxor behavior, with the Ce concentration improving energy recovery for storage applications.
