BaTiO3/YBa2Cu3O7-δ bilayer structures have been synthesized on SrTiO3 substrates using the pulsed laser deposition technique. The X-ray analyses show that the BaTiO3 films are highly c-axis oriented. In the studies of dielectric and ferroelectric properties of the BaTiO3 films, typical hysteresis loops and butterfly C-V plots are observed. The results indicate that the BaTiO3 films are promising in FRAM and related application fields.
