Magnetic properties of the suction-cast bulk amorphous alloy: (Fe_0.61Co_0.10Zr_0.025Hf_0.025Ti_0.02W_0.02B_0.20)₉₆Y₄

This paper presents the results of studies into the structural and magnetic properties of the bulk amorphous alloy: (Fe_0.61Co_0.10Zr_0.025Hf_0.025Ti_0.02W_0.02B_0.20)₉₆Y₄, fabricated in the form of rods of length: 20 mm, and diameters: 1 mm and 2 mm. The samples were produced using the suction-casting method. The amorphicity of the investigated alloy, in the as-quenched state, was verified using X-ray diffractometry and Mössbauer spectroscopy. Studies of the magnetic susceptibility disaccommodation and the approach to magnetic saturation facilitated the conclusion that the investigated alloy, obtained in the form of rods of 2 mm diameter, can be characterized by a higher packing density of atoms; this was further confirmed by the results of Mössbauer spectroscopy. - Highlights: • Samples were obtained using using the suction-casting method. • The samples were manufactured in the shape of rods of diameters 1 mm and 2 mm. • The amorphous structure was confirmed using XRD and Mössbauer spectroscopy. • Magnetic properties were analyzed in terms of contents of structural defects. • Time stability of magnetic properties was studied by disaccommodation phenomenon
