This paper presents the results of studies on the magnetic properties of the Fe60Co10Mo2Y8B20 alloy. The samples were fabricated in the form of plates by the injection-casting method. The structure of the investigated alloy, in the as-quenched state and after annealing, was veried by using X-ray diractometry. The magnetization curves as a function of temperature were measured by a force magnetometer. From thermomagnetic curves the Curie temperature of the alloy was determined. As a critical parameter β was chosen to be equal to 0.36 for these calculations, it conrmed that the alloys may be considered as ferromagnetic of the Heisenberg type. Additionally, using a vibrating sample magnetometer the magnetization and coercivity eld were studied (in magnetic eld up to 2 T).

“…The quenching speed of the molten alloy to the solid state determines the structural relaxations occurring in the alloy volume, which, in turn, strongly influences the properties of the resulting amorphous alloys [11,12]. An increase in the value of the viscosity of the alloy during the manufacturing process results in the restriction of the magnitude and rate of atomic diffusion.…”

“…An increase in the value of the viscosity of the alloy during the manufacturing process results in the restriction of the magnitude and rate of atomic diffusion. According to the investigations performed in [11][12][13][14], the structure and microstructure of samples produced at different cooling speeds influence directly the magnetic properties, despite the fact that the samples possess an amorphous structure. This conclusion proves that the atomic structure of amorphous materials depends on the cooling speed during the production process.…”

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.

The paper presents studies of the structural-defect influence on the magnetization process in low magnetic fields (H < 0.4 Hc) and above the Rayleigh range. The investigated Fe62Co10Y8B20 alloy samples were obtained with the injection casting method resulting in the amorphous-structure state, which was confirmed with XRD. The studies were conducted by analyzing the disaccommodation of the magnetic-susceptibility process and using Kronmüller's theory in the approach to the ferromagnetic saturation area. On the basis of the obtained results, it was found that the main factor responsible for the processes of magnetization in low magnetic fields are point defects, whereas in the case of high magnetic fields, the magnetization process depends mainly on second-type pseudo-dislocation dipoles. Keywords: metallic glasses, defects, disaccommodation, Kronmüller's theorŷ lanek predstavlja {tudij vpliva strukturnih defektov na proces magnetizacije v {ibkem magnetnem polju (H < 0,4 Hc) in nad Rayleigh podro~jem. Vzorci preiskovane zlitine Fe62Co10Y8B20 so bili izdelani z metodo injekcijskega brizganja, kar je povzro~ilo amorfno strukturo, ki je bila potrjena z rentgensko analizo (XRD). [tudije so bile izvedene z analizo procesa neustreznosti magnetne ob~utljivosti in z uporabo Kronmülerjeve teorije pri pribli`evanju feromagnetno nasi~enemu podro~ju. Na osnovi dobljenih rezultatov je bilo ugotovljeno, da so pri procesu magnetizacije glavni faktor to~kaste napake, medtem ko je v primeru magnetizacije v mo~nem magnetnem polju proces odvisen predvsem od druge vrste psevdodislociranih dipolov.
