Antisite Defects Stabilized by Antiphase Boundaries in YFeO₃ Thin Films

YFeO 3 thin films are a recent addition to the family of multiferroic orthoferrites where Y Fe antisite defects and strain have been shown to introduce polar displacements while retaining magnetic properties. Complete control of the multiferroic properties, however, necessitates knowledge of the defects present and their potential role in modifying behavior. Here, the structure and chemistry of antiphase boundaries in Y‐rich multiferroic YFeO 3...
