Fabrication and Domain Imaging of Iron Magnetic Nanowire Arrays



D Tulchinsky, Michael H. Kelley, Jabez J. McClelland, R Gupta, Robert Celotta


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.
