Abstract
The microstructure and magnetic properties, i.e. saturation magnetic polari zation, initial magnetic susceptibility and its disaccommodation, for the a morphous and the partially crystallized Fe73.5Cu1Nb3Si13.5B9 ribbons aged a t 733 K were studied. After accumulative annealing of the samples at 733 K, the decrease of the initial susceptibility and increase of the disaccommod ation intensities were observed. These are connected with the annealing out of 'free volumes' in the amorphous matrix, which is the main source of the magnetic after-effect in all investigated samples.
