In-plane magnetization of an ultrathin film of Fe3O4(111) grown epitaxially on Pt(111)

Abstract: The magnetic properties of an eight-monolayer ${\mathrm{Fe}}_{3}{\mathrm{O}}_{4}(111)$ film grown epitaxially on Pt(111) have been studied by the magneto-optic Kerr effect (MOKE) and conversion electron M\"ossbauer spectroscopy. The MOKE results indicate that a saturation of the magnetization is achieved with a field of about 500 Oe. In zero field the magnetization remains saturated. Apart from a paramagnetic contribution of 11%, which is interpreted as originating from the interface layer, the M\"ossbauer spectrum is identical to that of bulk ${\mathrm{Fe}}_{3}{\mathrm{O}}_{4}.$ Furthermore, the data indicate that all the magnetic moments are in the plane of the film.
