摘要：
A simple process has been developed to fabricate the magnetic nanocrystalline porous Co-Fe alloy microfibers with a hollow structure by the sol-gel and phase transformation at a low temperature. The alloy microfibers consisting of nanoparticles about 30 nm are characterized with a fiber diameter around 0.5 mu m, a ratio of the hollow diameter to the fiber diameter about 1/2 and pore sizes of 50 to 300 nm. These nanocrystalline porous Co-Fe alloy hollow microfibers have a good magnetic property, with the specific saturation magnetization of 212.8 A m(2) kg(-1) and coercivity of 15.6 kA m(-1) at room temperature.
