The aim of this paper was to conduct studies concerning the magnetization of bulk amorphous (Fe0.61Co0.10Zr0.025Hf0.025Ti0.02W0.02B0.20)97Y3 alloy when subjected to strong magnetic fields: the specific focus of the paper is the area known as the approach to ferromagnetic saturation. The investigated alloy samples were produced using the suction-casting method, resulting in plates of dimensions 10 mm× 5 mm× 0.5 mm and rods of length 20 mm and diameter 1 mm. The structure was studied using X-ray diffractometry. It was found that investigated samples were amorphous in the as-cast state. The magnetization was measured in a strong magnetic field using a vibrating sample magnetometer. On the basis of the obtained results, the type of structural defects having influence on magnetization in high magnetic fields were determined for the bulk metallic glasses manufactured with different cooling rates.
