Fecha de publicación: | 1-sep-2015 | Editor: | Elsevier | Citación: | Journal of Magnetism and Magnetic Materials 389: 144-147 (2015) | Resumen: | (Fe, Ni, CoFe) @ Au core-shell magnetic nanowires have been synthesized by optimized two-step potentiostatic electrodeposition inside self-assembled nanopores of anodic aluminium templates. The optimal electrochemical parameters (e.g., potential) have been firstly determined for the growth of continuous Au nanotubes at the inner wall of pores. Then, a magnetic core was synthesized inside the Au shells under suitable electrochemical conditions for a wide spectrum of single elements and alloy compositions (e.g., Fe, Ni and CoFe alloy). Novel opportunities offered by such nanowires are discussed particularly, the magnetic behavior of (Fe, Ni, CoFe) @ Au core-shell nanowires was tested and compared with that of bare nanowires. These core-shell nanowires can be released from the template thereby opening novel opportunities for biofunctionalization of individual nanowires. | Versión del editor: | https://doi.org/10.1016/j.jmmm.2015.04.059 | URI: | http://hdl.handle.net/10261/184167 | DOI: | 10.1016/j.jmmm.2015.04.059 | Identificadores: | doi: 10.1016/j.jmmm.2015.04.059 issn: 0304-8853 |
