Highly ordered magnetic Ni nanotubules (see Figure) have been successfully
prepared. Electrodeposition in the pores of an alumina membrane modified wi
th an organoamine as pore-wall modifying agent results in a perfectly order
ed array of such metal nanotubules tens of micrometers long. These metal na
notubules with open ends could be employed for the creation of materials wi
th special magnetic, optical, or electrical properties.
