Mixed-phase areas are produced in highly elongated BiFeO3 (BFO) thin films as a consequence of strain relaxation. A (001) neodymium aluminate (NdAlO3; NAO) substrate (a∼3.747 Å) prominently suppresses the strain relaxation effect and prevents the formation of mixed-phase regions. This creates a path...
