BiFeO₃ thin film prepared by pulsed laser deposition method onto the BaTiO₃ thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barrier height and then polarization of thin film can be opened the new insight in the ferroelectric devices.<!--stripped--><!--stripped--></p> magneto-electric thin films, Ferroelectric polarization, Pulsed laser deposition, Schottky barrier. 31 35 http://ijop.ir/browse.php?a_code=A-10-451-1&slc_lang=en&sid=1 Seyed Mohammad Hosein Khalkhali 10031947532846001508 10031947532846001508 Yes aDepartment of Physics, University of Kharazmi Mohammad Mehdi Tehranchi teranchi@sbu.ac.ir 10031947532846001509 10031947532846001509 No Department of Physics, G.C., Shahid Beheshti University Seyedeh Mehri Hamidi 10031947532846001510 10031947532846001510 No Laser and Plasma Research Institute, G.C., Shahid Beheshti University
