Ground State Monoclinic (M-b) Phase in (110) BiFeO3 Epitaxial Thin Films
The lattice structure of (110)-oriented BiFeO{sub 3} epitaxial thin layers has been identified by synchrotron x-ray diffraction. By using (221) and (22{bar 1}) peaks in the (HHL) zone, a ground state monoclinic M{sub b} phase has been observed with lattice parameters of ({beta}; a{sub m}/{radical}2 and c{sub m})=(89.35{sup o}; 3.985 and 3.888 {angstrom}). These results demonstrate a change in phase stability from rhombohedral in bulk single crystals, to monoclinic in epitaxial thin films with two domain states whose polarization is slightly tilted away from [110] towards [111].
