Fe nanowires 300 nm in width are fabricated from the epitaxial Fe film on Cu(001)/Si(001) by using laser interference lithography and chemical wet etching. The wire axis is parallel to the magnetic hard direction of the film. Scanning electron microscope and electron diffraction spectroscope spot profile analysis indicate that the isolated wires are successively fabricated. Although the Fe film shows intrinsic fourfold symmetry due to its crystallinity, the magnetic properties of the nanowires are strongly dominated by the uniaxial shape anisotropy.
