a- and b-axis-oriented (Bi_(3.25)Nd_(0.75))Ti_3O_(12) films, 3.0 mm thick, were fabricated on conductive IrO_2(101)/Al_2O_3(012) and Nb:TiO_2(101) [Nb = 0, 0.05 and 0.79 mass%] substrates by high-temperature sputtering. A BNT film grown on an IrO_2(101)/Al_2O_3(012) substrate had a low crystallinity (2.83˚), a low degree of a- and b-axis orientations [a_((h00/0k0)) = 49.2%] and a dense microstructure that a- and b-axis-oriented crystals existed locally in the film, while a BNT film grown on Nb:TiO_2(101) substrate with 0.79 mass% Nb showed a high crystallinity (0.57˚), a high a_((h00/0k0)) (99.9%) and a porous microstructure that was comprised of many nanoplate-like crystals. It is shown that the BNT film grew with a heteroepitaxial relationship to the underlying Nb:TiO_2 substrate has a symmetric loop shape, with a remanent polarization (2P_r) of 29 mC/cm^2 and a coercive field (2E_c) of 297 kV/cm.
