Abstract

We report a triclinic phase in perovskite BiFeO3 (BFO) epitaxial thin films grown on (130) and (120) oriented SrTiO3 substrates. The lattice constants of the BFO thin films changed with tilt of the substrates from (001) toward (110). These lattice parameters result from the epitaxially engineering of structurally bridging phases of the lowest possible symmetry.
