| 中文摘要 | Fe3Pt nanowire arrays were fabricated by electrodeposition of Fe2+ and Pt2+ into anodic aluminum oxide (AAO) templates. X-ray diffraction (XRD) pattern indicates that the crystallites of Fe3Pt nanowires are fcc structure with existence of strong [110] orientation along the nanowire axes. Transmission electron microscopy reveals that the diameter and length of nanowires are about 10 and 400 nm, respectively. Relatively high coercivities parallel to nanowire arrays of about 2.72 kOe at 5 K and 1.17 kOe at room temperature were achieved. The magnetic hysteresis loops demonstrate that the arrays of nanowires exhibit uniaxial magnetic anisotropy with the easy magnetization direction along the nanowire axes owing to the large shape anisotropy. The magnetization reversal process of the nanowire arrays at 5 K is discussed by symmetric fanning mechanism of sphere chains model. The temperature dependence of the coercivity parallel to nanowire arrays is interpreted by thermally activated magnetization reversal process. (c) 2005 American Institute of Physics. |
