Effects of annealing on the disaccommodation phenomenon in bulk metallic glasses (BMGs), obtained by injection-casting method have been studied. The amorphous structure has been confirmed using X-ray diffractometer. The annealing process has been performed at temperature below the crystallization temperature. For all investigated samples the disaccommodation curves have been determined. The susceptibility and its disaccommodation have been used in order to define thermal and time stability of magnetic properties. Obtained results have also been used to determine activation energies of elementary processes.
