The aim of this paper was to show the influence of the manufacturing method of bulk amorphous alloys on the resulting magnetization processes. Samples in the form of plates were prepared by the injection or suction of liquid alloy into a copper mould. In order to determine the type and quantity of structural defects present in the bulk amorphous alloys, the indirect method, i.e. the approach to the ferromagnetic saturation, was applied. Studies revealed the presence of conglomerates of point defects, for both alloys. These defects were pinning sites of domain walls and their number, size and type was found to have a direct impact on the coercive field. Alloy produced by the suction-casting method was found to possess the highest number of these defects, and thus a higher coercive field value.
