説明
MnPt3/Co multilayer films were grown by the molecular-beam epitaxy (MBE) onto MgO(111) substrates at a temperature of 300 °C. Small angle XRD measurements demonstrated that the samples had multilayered structure with sharp MnPt3/Co interfaces. The appearance of superlattice lines due to Cu3Au structure confirmed a partial formation of the ordered phase in the MnPt3 layers. The [MnPt3(1.9 nm)/Co(0.4 nm)]20 multilayer showed a preferential magnetization perpendicular to the film plane and a 100% perpendicular remanence. The Kerr spectrum of the multilayer had a negative peak of -0.24 deg around 1.4 eV and showed a enhancement in the high energy region. This result implies the existence of the ordered phase in the MnPt3 layer and alloying layer of Co and Pt at the MnPt3/Co interface.
