Application

Cobalt nanowires have been studied for their directional magnetic properties. In addition, cobalt nanowires have been studied for their magnetoresistance behavior at both room temperature and low temperatures. The metal nanostructure may be used to design thin film magnets with high energy density and high thermal stability.

Arrays of ferromagnetic nickel and cobalt nanowires have been fabricated by electrochemical deposition of the metals into templates with nanometer-sized pores prepared by nuclear track etching. These systems display distinctive characteristics because of their one-dimensional microstructure. The preferred magnetization direction
