Abstract
BiMnO3 has a centrosymmetric structure that precludes ferroelectricity in bulk stoichiometric samples while some films have reported ferroelectricity along with a decreased magnetic response. This puzzle motivated a study of one such film, deposited by pulsed laser deposition onto SrTiO3. Considering microscopy, diffraction, reflectometry, and x-ray absorption experiments in concert provide details of the structure and magnetism that suggest a deficiency of Bi and Mn metals stabilizes a multiphase system that explains the decreased magnetism. Film nanostructure and strain effects are also considered.Citation
