概要

• 論文の詳細を見る

• Ferromagnetic nanowires (NWs) of Fe–Co silicide have been formed successfully by the codeposition of Fe and Co onto a clean Si(110) surface at 750 °C in an ultrahigh vacuum (UHV). NWs up to 3.0 μm long are self-aligned along the Si[$\bar{1}10$] direction, owing to the low symmetry of the ideal Si(110) surface. Transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDX) reveal that NWs have a fluorite structure including both Fe and Co. Electron holography (EH) reveals that the magnetization of an NW is perpendicular to its long axis and is ca. $0.6\pm 0.1$ T at room temperature (RT).
