The as-grown polarizations of Mn- and Ti-doped Bi0.9La0.1FeO3 thin films (BLFMn and BLFTi) are demonstrated to align in an upward direction due to the occurrence of an internal bias field Ei that points up. On the basis of the conductivity and XPS as well as leakage current measurements, Ei in BLFMn...
