Growth and magnetism of self-organized arrays of Fe(110) wires formed by   deposition on kinetically grooved W(110)
  Homoepitaxy of W(110) and Mo(110) is performed in a kinetically-limited regime to yield a nanotemplate in the form of a uniaxial array of hills and grooves aligned along the [001] direction. The topography and organization of the grooves were studied with RHEED and STM. The nanofacets, of type {210}, are tilted 18&deg; away from (110). The lateral period could be varied from 4 to 12nm by tuning the deposition temperature. Magnetic nanowires were formed in the grooves by deposition of Fe at 150&deg;C on such templates. Fe/W wires display an easy axis along [001] and a mean blocking temperature Tb=100K
