Evolution of structure-scaling and magnetic properties during thermal loading of melt-spun Fe_(70)Cr_(15)B_(15)(Sn) alloys

摘要

We have studied the scaling evolution of the structure and magnetic properties of the melt-spun Fe_(70)Cr_(15)B_(15)(Sn) alloys. The magnetic percolation cluster about the percolation threshold forms at the vitrification stage that is determined by both the kinetics of magnetic and of transport properties and the variation of fractal dimensionality. Alloying by tin of contact surface of ribbon decreases the temperature of the cluster formation. It is shown that the evolution of a fractal ordering affects the kinetics of the physical properties of the alloys. The spectra of fractal dimensionality identify the symmetry character of melt-spun alloys. Fractal dimension D_f is reduced at the increasing complexity of hierarchical system.
