Abstract

Multiferroic $BiFeO_3$ thin films have been deposited on $Pt/TiO_2/SiO_2/Si$ substrates by pulsed-laser deposition. From the X-ray diffraction analysis, the $BiFeO_3$ thin film consists of perovskite single-phase and shows a tetragonal structure with a space group P4mm. Ferroelectric hysteresis saturate well and a remanent polarization is 73 ${\mu}C/cm^2$ for a maximum applied voltage of 4 V. A saturated ferromagnetic hysteresis loop has been also obtained and a saturation magnetization is 3.5 $emu/cm^3$ for a maximum magnetic field of 10 kOe at room temperature.
