To develop silicon-based spintronic devices, we have explored high-quality ferromagnetic Fe(3)Si/silicon (Si) structures. Using low-temperature molecular beam epitaxy at 130 C, we realize the epitaxial growth of ferromagnetic Fe(3)Si layers on Si (111) with an abrupt interface, and the grown Fe(3)Si layer has the ordered DO(3) phase. Measurements of magnetic and electrical properties for the Fe(3)Si/Si (111) yield a magnetic moment of similar to 3.16 mu(B)/f.u. at room temperature and a rectifying Schottky-diode behavior with the ideality factor of similar to 1.08, respectively.
