摘要：
The magnetic properties and the annealing process of Fe(78)Zr(7)B(15) amorphous ribbons are investigated by X-ray diffraction (XRD), differential scanning calorimetry, and vibrating sample magnetometer. The fully amorphous structure of the as-quenched ribbons is confirmed by the XRD pattern. The Curie temperature and the saturation magnetization M(s), of the ribbons are 305 degrees C and 124.3 emu/g, respectively. Annealing at 550 degrees C can result in an increase in M(s), with annealing time due to the increasing crystallized volume fraction of alpha-Fe phase. The optimized annealing process is established at 550 degrees C for 20-30 min with maximum M(s) of 146.6 emu/g. The morphology of the ribbons annealed at 550 degrees C is observed by scanning electron microscopy, showing that nanocrystalline alpha-Fe grains are dispersed in an amorphous matrix.
