Abstract

The structural and ferroelectric domain variants of highly strained BiFeO ₃ films grown on vicinal LaSrAlO ₄ substrates were studied by piezoelectric force microscopy and high-resolution x-ray reciprocal space mapping. Through symmetry breaking of the substrate surface, ferroelastic domain variants in the highly strained M _C phase BiFeO ₃ can be greatly reduced in thinner, purely tetragonal-like films. More interestingly, in thicker, mixed phase films, the structural variants can also be tailored by substrate vicinality. These findings lead to better understanding of the phase evolution and polarization rotation process in the strain-driven polymorphic phase system. © 2012 American Institute of Physics.
