We show that simultaneous doping of Bi along with Fe into BaTiO 3 effectively enhances the magnetoelectric (ME) multiferroic response (both ferromagnetism and ferroelectricity) at room temperature, through careful tuning of Fe valency along with the controlled recovery of the ferroelectric-tetragonal phase.

TSDC of the pure BaTiO 3 ceramic shows one peak, whereas Fe-doped ceramic shows two peaks. The first and second peaks are presumably ascribed to defect dipole and space charge polarization, respectively.
