Abstract

The influence of the thermal treatments on the effective magnetic anisotropy of Co₆₆Fe₄Mo₂Si₁₆B₁₂ metallic glass is examined through the results corresponding to the measurement of the transverse-biased initial susceptibility (χ_t). The annealing lead to a remarkable improvement of the magnetic softness, reaching the optimum properties at 648 K and 60 min. The analysis of the χ_t data in terms of the micromagnetic magnetization ripple theory allowed us to evidence the occurrence in the annealed samples of coupled magnetization regions larger than the average grain size.
