Template Synthesis of an Array of Nickel Nanotubules and Its Magnetic Behavior

Abstract

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