AbstractDouble-perovskite films have been extensively studied in multifunctional fields due to their modifiability. Here, a controlled process strategy to induce chemical strain and anomalous Poisson deformation is proposed for perovskite-based films. The chemical negative strain in the local-ordering BiSmFe2O6 double-perovskite films can be regulated by oxygen engineering to cause the effectively tunable bandgap.
