BiFeO<inf>3</inf>-PbTiO<inf>3</inf> (BFO-PT) thin films were fabricated by sol-gel technology. X-ray diffraction pattern reveals the BFO-PT films are in rhombohedral perovskite phase with random orientations. By Pt/BFO-PT/ITO/glass capacitor structure, co-measurement of electrical and optical responses can be achieved. Remanent polarization of(More)
Bismuth ferrite and lead titanate composite multiferroic films (xBiFeO<inf>3</inf>-(1-x)PbTiO<inf>3</inf>, BFO-PT films) were deposited on Pt/Ti/SiO<inf>2</inf>/Si substrates by sol-gel method. In this report, the value of x varies from 0.5 to 0.8. The composition dependence (dependence of x) of BFO-PT films is studied. X-ray diffraction analysis reveals(More)
The exhibiting electrical properties of ferroelectric thin films usually are influenced by the electrode materials. In this paper, platinum (Pt), gold (Au) are selected as the top electrode materials for 0.6(Bi<inf>0.85</inf>La<inf>0.15</inf>)FeO<inf>3</inf>-0.4PbTiO<inf>3</inf> (BLFO-PT) thin films. The Pt and Au electrodes were prepared by sputtering(More)
