Thermal Stability of Nanocrystalline Soft Magnetic Alloys with Different Inhibitors

Abstract:

In this work, the effect of different inhibitors on the thermal stability of the magnetic properties in Fe_73.5Cu₁M₃Si_13.5B₉ nanocrystalline alloys, where M = Nb, W, Mo, was investigated. Nanocrystalline alloy with tungsten has the greatest thermal stability. The change in the magnetic properties in the ageing process was associated with vacancies and vacancy clusters, the formation of which is facilitated by large atoms of inhibitory elements occupying free positions in the substitution solid solution.
