To develop silicon-based spintronic devices, we have explored high-quality ferromagnetic Fe3 Si /silicon (Si) structures. Using low-temperature molecular beam epitaxy at 130 °C, we realize the epitaxial growth of ferromagnetic Fe3 Si layers on Si(111) with an abrupt interface, and the grown Fe3 Si layer has the ordered D O3 phase. Measurements of magnetic and electrical properties for the Fe3 SiSi (111) yield a magnetic moment of ∼3.16 μB f.u. at room temperature and a rectifying Schottky-diode behavior with the ideality factor of ∼1.08, respectively.
