The effect of the temperature of nanocrystallizing annealing (NA) at temperatures of 670-750°C on the magnetic properties, structure, and thermal stability of the [([Fe.sub.0.7][Co.sub.0.3]).sub.88][Hf.sub.2][W.sub.2][Mo.sub.2][Zr.sub.1][B.sub.4][Cu.sub.1] alloy has been studied. The NA was performed both in the presence of tensile stresses applied to samples and in the absence of stresses. It was found that the nanocrystallization of the alloy under applied tensile stresses induces the longitudinal magnetic anisotropy with an easy magnetization axis parallel to the long side of the ribbon. The optimum conditions for nanocrystallization of the alloy, which stabilize its magnetic properties at a fairly high temperature of 570°C, have been determined.
