摘要：
The work presents a study on the influence of high-speed nonequilibrium of the melt -spinning process on the morphological and magnetic properties of the amorphous Co58Ni10Fe5Si11B16 alloy. It is shown that the amorphous states with a different extent of disordering may be produced by varying the melt-spinning conditions. A correlation has been established between the fractal structure of morphological inhomogeneities and the magnetic properties of the melt-spun alloy: the higher the fractal dimension of the hierarchical mesoscale structure, the more the soft magnetic alloy. The optimal ordering of both the morphological and magnetic structure of the melt-spun Co58Ni10Fe5Si11B16 alloy is achieved at a cooling roller speed of 28 m/s.
