In this paper we report synthesis of phase-pure highly resistive magnetoelectric BiFeO3 thin ???lms on Pt/TiO2/SiO2/Si substrate by using pulsed laser deposition technique. For the ???rst time saturated ferroelectric hysteresis loop has been observed. It has con???rmed the presence of ferroelectricity in BiFeO3 compound. The ???lms exhibit dielectric anomaly near Neel temperature. This anomaly is related to the in???uence of vanishing magnetic order on the electric order. In situ domain alignment occurs during observation of the ???lms under transmission electron microscope.
