Abstract	Fe-doped BaTiO3 thin films were grown on (001) oriented SrTiO3 substrates using pulsed-laser deposition technique. These films had a single-phase character and good epitaxial relationship with the substrate. Polarization-electric field (P-E) hysteresis revealed a saturated polarization with a remnant polarization (Pr) of 13.5 $μC/cm^{2}$ for 10 mol% Fe-doped BaTiO3 films. Further increase of composition resulted in the large leakage currents and reduction of polarization. The piezoelectric domain switching in the films was confirmed by local hysteresis using piezoelectric force microscopy measurements. The Fe-doped BaTiO3 thin films exhibited room temperature ferromagnetism, and the magnetization value increased with increasing Fe concentration. Our results demonstrated that the addition of Fe ≤10 mol% in BaTiO3 induce the ferromagnetism and the switchable ferroelectric state.
