“…In ferroelectric thin films formed with perovskite structures, such as Pb(Zr,Ti)O 3 (PZT), spontaneous polarization is formed as the octahedrons constituting the perovskite structures are elongated. [1][2][3][4][5] The deformation of octahedrons of ferroelectrics having the perovskite structure can be maximized by external stress caused by doping of transition metals. [6][7][8] In addition, ferroelectric thin films having perovskite structures can have improved ferroelectric properties due to lattice mismatch with the bottom electrodes.…”

We investigated the ferroelectric switching dynamics as well as the multiferroic and piezoelectric properties of highly a‐oriented epitaxial Bi5Ti3FeO15 (BTFO) thin films on Nb‐doped SrTiO3 single crystal substrates. The BTFO thin films favored highly a‐oriented crystallinity because c‐oriented crystallinity decreased under deposition conditions in which substrate temperature and thin film deposition rate were simultaneously lowered. The highly a‐oriented epitaxial BTFO thin films showed the best ferroelectric properties, whereas the highly c‐oriented epitaxial BTFO thin films showed the best ferromagnetic properties. In particular, the BTFO thin films in which a‐ and c‐oriented crystallinity were properly mixed showed the best piezoelectric properties.
