Abstract—The influence of nanocrystallization conditions on the structure, magnetic properties, and temper-
ature stability of nanocrystalline magnetically soft Fe_73.5Cu₁Nb_1.5Mo_1.5Si_13.5B₉ alloy is studied. It is found that
preliminary low-temperature annealing exerts an influence on subsequent nanocrystallization of the alloy. In
addition, preannealing followed by nanocrystallization considerably improves the magnetic properties of the
alloy. It is shown that the magnetic properties of the material can be controlled by varying the frequency of a
magnetic field used for thermal treatment causing nanocrystallization. It is established that the magnetic prop-
erties of nanocrystalline Fe_73.5Cu₁Nb_1.5Mo_1.5Si_13.5B₉ alloy offer a high temperature stability.
