Synthesis and Magnetic Properties of FePt Fe₃Pt Nanowire Arrays Embedded in Anodic Alumina Membranes

摘要

FePt Fe₃Pt nanowire arrays embedded in the nanochannels of anodic alumina membranes (AAM) were successfully fabricated by electrodeposition. X-ray diffraction (XRD) pattern indicates that the crystallites of FePt Fe₃Pt nanowires embedded in AAM are face centered cubic structure. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) reveal that the diameter and the length of nanowires are about 60 nm and 1 μm, respectively. The magnetic hysteresis loop demonstrates that the arrays of FePt Fe₃Pt nanowires system exhibit uniaxial magnetic anisotropy with the easy magnetization direction along the nanowire axes owing to the large shape anisotropy.View full textDownload full textKeywordsNanowire, magnetic propertiesRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10584587.2012.685406
