Synthesis and characterisation of fluorinated epitaxial films of BaFeO₂F: tailoring magnetic anisotropy<i>via</i>a lowering of tetragonal distortion

Abstract

F. Surprisingly, fluorination resulted in the change of the tetragonal distortion to a nearly cubic symmetry, which results in a lowering of anisotropic orientation of the magnetic moments of the antiferromagnetically ordered compound, confirmed by Mössbauer spectroscopy and magnetic studies.
