Opis:
The aim of this paper was to conduct studies concerning the magnetization of bulk amorphous $(Fe_{0.61}Co_{0.10}Zr_{0.025}Hf_{0.025}Ti_{0.02}W_{0.02}B_{0.20})_{97}Y_{3}$ 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.

Opis:
Amorphous materials contain structural defects, which play a key role in the magnetization process within the condition known as the "approach to ferromagnetic saturation". This paper presents the results of magnetization studies, carried out on bulk Fe₆₁Co₁₀Ti₃Y₆B₂₀ alloy when under the influence of a strong magnetic field. The alloy samples were obtained in the form of a rod 1 mm in diameter, and tested in the as-quenched state and after an isothermal annealing process, at a temperature below the crystallization temperature. It was observed that the heat treatment, carried out below crystallization temperature Tₓ, leads to irreversible structural relaxations, specifically reorganizing the atomic configuration within the volume of the alloy into an amorphous structure.

Opis:
In this paper, the results of structural and magnetic investigations are presented for the following amorphous alloys: FeMeMoCrNbB (where Me = Ni or Co). The structural investigations were performed using X-ray diffractometry. It was found that the investigated samples were amorphous in the as-cast state. The magnetisation was measured within magnetic fields ranging from 0 to 1 T using a vibrating sample magnetometer. Investigation of the "magnetisation in the area close to ferromagnetic saturation" showed that the magnetisation process in strong magnetic fields is connected with the rotation of magnetic moments in the vicinity of defects, which are the sources of short-range stresses. Analysis of the high-field magnetization curves facilitated the calculation of the spin-wave stiffness parameter.

Opis:
The study analyzed the influence of structural defects on the process of magnetization in the area called the approach to ferromagnetic saturation for bulk $Fe_{60}Co_{10}W_xNb_2Y_{8}B_{20-x}$ (x=0, 1) alloys. For this purpose, the magnetization studies were performed in the fields range of 0 T to 2 T using a LakeShore vibrating magnetometer. On the basis of the Kronmüller theory an analysis of the magnetization curves was conducted and the type of occurring structural defects in the studied alloys was established. Then, using a Monte Carlo method the effective anisotropy of the tested samples was designated.

Opis:
Possibility of decomposing the static hysteresis loop is demonstrated. The applied method is related with decomposition of experimentally obtained reversal magnetization curve on the reversible and irreversible components. Results are applicable in analysis of reversal magnetization processes in hard magnetic materials and for simulation of hysteresis loop using hyperbolic T(x) model.
