摘要：
Nd8.1Dy0.9Fe76.95Co8.55B5.5 nanocomposite magnets annealed with and without a 10 T magnetic field were inves-tigated in this article. The ribbons with coexisting amorphous and crystalline phases were selected to do this study. The re-sults of M?ssbauer spectroscopy revealed that the content of α-Fe increased when annealed in high strength magnetic field. The size of the grains also increased considerably after the application of magnetic annealing. All these led to the decrease of the magnetic properties, especially the coercivity of the ribbons.
