Intermediate multidomain state in single-crystalline Mn-doped BiFeO₃ thin films during ferroelectric polarization switching.

ABSTRACT: A intermediate multidomain state and large crystallographic tilting of 1.78° for the (hh0)_pc planes of a (001)_pc-oriented single-domain Mn-doped BiFeO₃ (BFMO) thin film were found when an electric field was applied along the [110]_pc direction. The anomalous crystallographic tilting was caused by ferroelastic domain switching of the 109° domain switching. In addition, ferroelastic domain switching occurred via an intermediate multidomain state. To investigate these switching dynamics under an electric field, we used in situ fluorescent X-ray induced Kossel line pattern measurements with synchrotron radiation. In addition, in situ inverse X-ray fluorescence holography (XFH) experiments revealed that atomic displacement occurred under an applied ele
