Microstructures and magnetic properties of Tb-Fe-Co magnetic nanowire arrays prepared by electrochemical deposition

Highly ordered Tb-Fe-Co nanowires have been synthesized from Tb-Fe-Co aqueous solution by direct current electrochemical deposition with anodic alumina templates for the first time. In this work, the effects of interface coupling on the magnetic properties of Tb-Fe-Co nanowires are studied mainly. Comparing with the magnetic properties of Fe-Co nanowires, the coercivity and remanence ratio of annealed Tb-Fe-Co nanowires doped with Tb element increase significantly. Therefore, the study about the impacts of doping rare earth elements Tb in Fe-Co nanowires may provide a meaningful way to improve the properties of magnetic recording materials, meanwhile Tb-Fe-Co nanowires will certainly play an important role in future device research of magnetic recording devices.
