- Аннотация: The optimization of soft magnetic materials for high-frequency and energy-efficient applications requires afundamental understanding of the interplay between microstructure evolution and magnetic properties duringthermal processing. This work investigates the magnetization relaxation kinetics during the crystallization ofFeCoNiSiNbB amorphous ribbons using in-situ vibrating sample magnetometry. The crystallization proceeds via atwo-stage process, forming first a cubic and then a hexagonal phase. The temperature dependence of the effectiveanisotropy constant, a key parameter, was determined experimentally. Analysis reveals a direct link between this evolution and a non-monotonic temperature dependence of the characteristic relaxation time. We develop a phenomenological model that successfully describes this behavior by summing contributions from the growth of both crystalline phases and a term accounting for the experimentally measured anisotropy. The results demonstrate that accurate modeling of magnetic relaxation during crystallization must explicitly include thesemicrostructural changes, providing a practical framework for optimizing soft magnetic alloys. This work provides a refined microstructural and kinetic framework for tailoring the magnetic properties of advanced soft magnetic alloys through precise control of crystallization.
