摘要
We have synthesized high-quality BiMnO3 thin films on Nb-doped SrTiO3 substrates with (100), (110), and (111) orientations. All the films with different orientations undergo ferromagnetic transitions at approximately the same temperature (∼105 K) as bulk BiMnO3 does. The magnetic easy direction was also found to be the monoclinic [010]m direction in accordance with the bulk case. Detailed measurements of ferroelectric characteristics such as the P — E hysteresis loops and the piezoelectric coefficient d33 did not show any significant evidence of ferroelectricity in any of the films.
