Arrays of magnetic nanowires are fabricated by using a corrugated surface, produced by chromium atoms laser-focused in a one-dimensional standing wave, as a shadow mask for an iron evaporator. The deposited iron forms a periodic array consisting of thousands of 20-40nm high ferromagnetic lines with width of ~ 100nm, spaced every 213nm, and having aspect ratios of 1:1500. Images of the magnetic domain structures of these nanowires are obtained by scanning electron microscopy with polarization analysis (SEMPA). Elongated domains ~100nm wide and ~ 16 υm long are observed.
