Tetragonally strained BiFeO3 thin film on single crystal Rh substrate

► Fabrication of epitaxial (001) BiFeO3 thin films having the tetragonally stained structure with a c/a ratio of about 1.04 on single crystalline (100) Rh substrates. ► The BiFeO3 thin film showed a high remanent polarization (Pr) of about 91 μC/cm2. ► The enhanced remanent polarization due to the large stripe domain structure that originated from the high domain wall energy.
