Strain-induced change in magnetic anisotropy in monodomain BiFeO3 films. a Schematic of a (110)-oriented BiFeO3 crystal structure wherein the polarization P, oxygen octahedral rotation axis D (blue arrow), easy-magnetic plane (orange hexagon), antiferromagnetic-spin axis L (red arrow), and canted moment M (orange arrow) are drawn. b Example reciprocal space mapping result, here for a 70-nm-thick BiFeO3/GdScO3 (010)O heterostructure, about the 042O- (221-) diffraction conditions of GdScO3 (pseudocubic BiFeO3). No peak splitting is observed, indicating that the film has single ferroelastic domain structure. c Polarization-dependent X-ray absorption spectroscopy (XAS) and d X-ray linear dichroism (XLD) spectra at normal incidence about the Fe L2,3 edge taken on 70-nm-thick BiFeO3/GdScO3 (010)O and SrTiO3 (110) heterostructures
