Effect of Annealing Temperature on the Structures and Properties of Bi4.15Nd0.85Ti3FeO15 Thin Films

Article Preview

Abstract:

To investigate the effect of annealing temperature on the structures and properties of Bi4.15Nd0.85Ti3FeO15 (BNTF), their thin films with four perovskite slabs were deposited on Pt/Ti/SiO2/Si substrates by the metal-organic decomposition method. Good remanent polarization and excellent fatigue resistance were observed at room temperature. The BNTF thin films annealed at 780°C presented better ferroelectricity than those annealed at 700°C-780°C. Ferromagnetic of BNTF thin films was not observed at room temperature.
