Ni was e-beam evaporated under a shallow angle of incidence onto a lithographically structured Si substrate with submicrometer grating. By pure geometrical shading effects, 10nm wide Ni nanowires were deposited spaced at 750nm. In order to prevent the Ni from oxidization a 10nm thick Al capping layer was additionally sputter deposited.

The structural properties of the such prepared Ni nanowires were studied using x-ray scattering and atomic force microscopy techniques. Results on the magnetic behaviour were obtained by neutron scattering and magnetic force microscopy.
