Opis:: Structure and hyperfine interactions of amorphous and nanocrystalline FINEMET were investigated by means of Mössbauer spectrometry. It was found that substitution of x iron atoms with aluminum ones causes changes in the properties of both amorphous and nanocrystalline alloys as well as in the structure of individual phases. The reduction of hyperfine magnetic field caused by atom substitution is a non-linear function of x, unlike the linear dependence expected because of dilution. Temperature studies reveal a double magnetic phase transition at 250°C and 330°C as well as point to the variety of phases in the examined material.

Opis:: In this work hyperfine fields of two-phase nanocrystalline Fe72Cu1.5Nb4Si13.5B9 alloys were studied in order to verify the existence of surface effects. To obtain a series of nanocrystalline samples with small grains of different sizes, a special non- -isothermal annealing procedure of an initially amorphous ribbon was applied. In the case of samples with a significant amount of crystallites, a high field (about 27.5 T) component of continuous part of the hyperfine field distribution was found that could be attributed to boundary regions between the grains and rest of the sample. The existence of the surface effects was confirmed in the magnetostrictive experiment.

Opis:: Recent development of SPICE, FEM and MoM software often requires the fast and reliable description of BH saturation magnetization curve. In spite of the fact that physical models of BH saturation curve are very sophisticated, for technical purposes, such curve may be modelled by simplified equations. Paper presents the quantitative assessment of the quality of four technical models of BH saturation magnetization curve performed for four modern magnetic materials: constructional corrosion resistant steel, Mn-Zn ferrite, amorphous alloy with perpendicular anisotropy as well as Finemet-type nanocrystalline magnetic material. Presented results confirm reliability of the model as well as indicate that high-speed calculation may be done using arctangent function.
