“…It also follows from Figure 23 that the experimental constant determined from the magnetization work agrees well with the constant determined from the initial permeability µ i in the model of magnetization rotation: (17). Reproduced with permission from [110]. Figure 24 shows the dependences of temperature T and initial permeability µ i at a frequency of 1 kHz on time t during crystallization of Fe 72.5−x Ni x Cu 1 Nb 2 Mo 1.5 Si 14 B 9 alloys with x = 0 and 8.5 at.…”

“…The introduction of Ni and Co soluble in α-Fe into a nanocrystalline alloy leads to an increase in the magnetic anisotropy constant K u induced in a magnetic field [109]. Figure 23 shows the dependence of the magnetic anisotropy constant K u on the Ni content in the Fe 72.5−x Ni x Cu 1.1 Nb 1.9 Mo 1.5 Si 14.3 B 8.7 alloy [110]. Linearity of the curve up to a Ni content of 7 at.…”

The review is devoted to the analysis of physical processes occurring at different stages of production and application of nanocrystalline soft magnetic materials based on Fe–Si–B doped with various chemical elements. The temperature dependences of the kinematic viscosity showed that above a critical temperature, the viscosity of multicomponent melts at the cooling stage does not coincide with the viscosity at the heating stage. Above the critical temperature, the structure of the melt is more homogeneous, the amorphous precursor from such a melt has greater plasticity and enthalpy of crystallization and, after nanocrystallization, the material has a higher permeability. The most effective inhibitor elements are insoluble in α-Fe and form a smoothed peak of heat release during crystallization. On the other hand, the finest nanograins and the highest permeability are achieved at a narrow high-temperature peak of heat release. The cluster magnetic structure of a nanocrystalline material is the cause of magnetic inhomogeneity, which affects the shape of the magnetic hysteresis loop and core losses.
