Abstract: Antiferromagnetic domains in an epitaxial thin film, LaFeO3 on SrTiO3(100), were observed using a high-spatial-resolution photoelectron emission microscope with contrast generated by the large x-ray magnetic Linear dichroism effect at the multiplet-split L edge of Fe. The antiferromagnetic domains are linked to 90 degrees twinned crystallographic regions in the film. The Neel temperature of the thin film is reduced by 70 kelvin relative to the bulk material, and this reduction is attributed to epitaxial strain. These studies open the door for a microscopic understanding of the magnetic coupling across antiferromagnetic-ferromagnetic interfaces.
