摘要Arrays of FeCo nanotubes are fabricated in the pores of porous anodic aluminium oxide templates. Transmission electron microscopic result shows that the nanotubes are regular and uniform. Magnetic hysteresis loops measured at room temperature are different from those of nanowires with the same composition, which are caused by the unique shape of nanotubes. The Mossbauer spectra show that the hyperfine field is smaller than that of the bulk's and increases with decrease of measuring temperature. However, the areas of the doublets appeared in Mossbauer spectra decrease with decrease of measuring temperature.
