The project aims at studying the surface/interface effects such as surface magnetic anisotropy and interfacial Dzyaloshinskii-Moriya interaction (iDMI) in full-Heusler alloys ultrathin films showing perpendicular magnetic anisotropy (PMA) and to test their potential of integration in spintronic devices. The multilayer architectures will be epitaxially grown on single-crystal substrates and textured grown on thermally oxidized Si/SiO2 substrates. The textured structures are of extreme importance due to their compatibility with the conventional microelectronics technology. Our upstream research strategy is expected to have a major impact on the development of spintronics based on half-metallic materials, allowing enhanced data storage and data processing speed, low power consumption and high level of downscaling of the device dimensions. All these aspects are fully compatible with the needs of the next generation of spintronic devices.
