Two tilted triclinic phases were found via synchrotron x-ray diffractions in the mixed-phase regions of highly strained BiFeO3 films. First-principles calculations suggest that these two triclinic phases originate from a phase separation of a single monoclinic state accompanied by elastic matching b...
