The evolution of the structure in ferromagnetic amorphous alloys is difficult to characterize and work is ongoing to describe it. Generally, in the literature on the subject it is difficult to find publications on the description of changes in the amorphous structure and their impact on magnetic properties. The paper presents results of research on the structure and magnetic properties of iron-based bulk amorphous alloys. Alloys with chemical composition Fe65Nb5Y5+xHf5-xB20 (where: x = 0, 1, 2, 3, 4, 5) were produced using the injection casting method. Structure of the materials was examined using X-ray diffraction. Magnetic properties were determined using a vibrating sample magnetometer. An attempt was made to relate the X-ray diffraction images with the magnetic properties of produced alloys. It has been shown that in the case of investigated alloys there is a relationship between the value of the coercive field and the width and location of the maximum corresponding to the amorphous phase. A similar relationship was found for the Curie temperature value. In addition, saturation magnetisation was found to be associated with maximum intensity. •New bulk amorphous alloys FeNbYHB with good soft magnetic properties.•The shape of the diffractograms is related to the magnetic properties.•Saturation magnetisation is associated with maximum intensity.•Coercive field is associated with width and location of the amorphous halo.
