The results show that Fe0.13[Co20Ni80]0.87 alloy fibers are characterized with thin diameters between 0.3 and 2.0 μm, with high aspect ratio, dense and smooth surfaces. The crystalline size of the alloy fibers are mainly influenced by the thermal reduction temperature and are in the range of 20 to 50 nm with a corresponding reduction temperature range of 300 to 700 ℃. The magnetic properties of the alloy fibers are largely affected by the carbon content and crystalline sizes of the alloy fibers. With increasing thermal reduction temperature, the coercivity decreases while the saturation magnetisation value of the alloy fibers dramatically increases at lower reduction temperatures. The alloy fibers prepared at reduction temperature of 700 ℃ have a saturation magnetisation value of 120 Am2/kg and a coercivity value of 10.4 kA/m, respectively.
