The influence of Fe72.5Cu1Nb2Mo1.5Si14B9 nanocrystalline alloy annealing temperature on the structure and magnetic properties has been investigated. The heat treatment temperature of nanocrystalline soft magnetic alloy Fer2.5Cu1Nb2 Mo1.5Si14B9, which allows reaching the maximum value of the initial magnetic permeability, was found to be 15-20° higher than that ensuring the minimum coercive force. The relation between the numerical values of the coercive force, the initial magnetic permeability and the magnetic hysteresis loop rectangularity factor allows optimizing the mode of nanocrystalline alloy heat treatment.
