Abstract

We reported that the tetragonal-like phase identified in strained epitaxial BiFeO₃ films on a (001) LaSrAlO₄ single crystal substrates is monoclinic M_C, based on high resolution synchrotron x-ray studies and piezoresponse force microscopy measurements. This M _C phase has different symmetry with the rhombohedral-like monoclinic M_A phase found in BiFeO₃ films grown on low mismatch SrTiO₃ substrates. Transmission electron microscopy revealed that the films on LaSrAlO₄ substrates have a high crystalline quality and coherent interface. © 2010 American Institute of Physics.
