“…[22] The higher value of the average induction of the hyperfine field for the plate-shaped sample suggests a higher value of atomic packing density, in comparison with the ribbon-shaped sample. In turn, this suggests a higher degree of order in the topological structure of the plate-shaped sample.…”

This paper presents the results of investigations into the structure, microstructure and magnetic properties of Fe61Co10Y8W1B20 amorphous alloy. The alloy samples were in two physical forms: (1) plates of approximate thickness 0.5 mm (so-called bulk amorphous alloys) and (2) a ribbon of approximate thickness 35 μm (so-called classic amorphous alloy). The investigations comprised: X-ray diffractometry, Mössbauer spectrometry, transmission electron microscopy, and selected magnetic measurements; all of the investigations were carried out on samples in the as-quenched state. Analysis of the obtained SEM and TEM images, X-ray diffraction patterns, Mössbauer spectrometry results and measurements of the magnetisation in a high magnetic field facilitated collectively the detailed description of the structure of the investigated alloy, which was found to depend on the quenching speed.

“…Those samples were interesting enough to become a research material for materials engineering and physics specialists. FeCoB based amorphous alloys that demonstrate so called soft magnetic properties proved to be of special interest [11][12][13][14]. The amorphous tapes based on FeCoB experience significantly lower losses during magnetization reversal than FeSi transformer steels used in the electro technical industry [15].…”

The paper presents the research results for the Fe 78 Co 2 Si 9 B 11 amorphous alloy, and after the process of annealing resulting only in the relaxation of the material. The structure relaxations occurring in the volume of test samples lead to the changes in their magnetic and mechanic properties. Therefore the studies on the effect of the structure defects on the properties of these type of materials are important. Understanding the processes occurring during the magnetizing of amorphous alloys can be helpful in the design of modern functional materials for special purposes. The main purpose of this elaboration was to determine the effect of the amorphous structure defects in the state after solidification and after heat treatment on the changes in the magnetizing process and in such parameters as the saturation magnetization and the coercivity field.

This paper presents the results pertaining to thermal and magnetic studies of rapidly-cooled samples of the alloy family Fe61Co10B20Y8Me1 (where Me = Nb, Zr, W, Mo). The resulting ribbons, or tapes, have amorphous structure. It has been found that the addition of Me elements alters the thermal and magnetic properties. It is noted that the saturation magnetization decreases with increasing number of unpaired electrons on the valence shells. In addition, the value of the coercivity and effective anisotropy have been determined.
