The microstructure, magnetic susceptibility and its disaccommodation for the amorphous and partially crystallized Fe86Zr7B6Cu1 ribbons are investigated. Due to the stress relief, the decrease of the Curie temperature after the annealing of the sample at 573 K is observed. Moreover, this treatment leads to the decrease of the average hyperfine field. The sample containing 7 % of αFe phase exhibits a superparamagnetic behaviour. The disaccommodation of the magnetic susceptibility in partially crystallized ribbons is connected with the relaxation processes occurring in the amorphous matrix.
