Their ferroelectric behaviour is strongly dependent on the film composition and orientation. 0.95BiFeO3-0. 05(Bi0.50Na0.50) TiO3 (BFOBNT5) exhibits notably better ferroelectric behaviour and fatigue endurance than the films of other compositions. The largest spontaneous polarization occurs in its (1 1 1) direction, where a remanent polarization of 2Pr ∼ 198.3 νC cm-2 is measured, while the polarizations in other directions are consistent with the projections from the (1 1 1) direction. © 2009 IOP Publishing Ltd.||Source Title:||Journal of Physics D: Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/86575||ISSN:||00223727||DOI:||10.1088/0022-3727/42/19/195405|
