Opis:: In this paper we present experimental results on influence of Al content on the structure and saturation magnetostriction of Fe-Al-Cu-Nb-Si-B alloys after heat treatment. Transmission electron microscopy observations confirmed the existence of nanocrystalline structure after annealing at 490°C and 550°C for all samples. The crystallization temperature of FeSi phase and the temperature at which the polycrystalline transformation starts were determined from temperature dependence of electrical resistivity. Aluminium slightly decreases the first crystallization temperature and considerably decreases the saturation magnetostriction in as-quenched state.

Opis:: The effect of addition of Co and V on the hyperfine parameters of amorphous as well as nanocrystalline Finemet-type alloys has been studied by means of transmission Mössbauer spectrometry. It was stated that these elements infiltrate into crystalline grains in the course of crystallization, what causes alteration in structure. Different evolution of magnetic hyperfine field is reported in both cases and analyzed. In the series of alloys substituted by vanadium, the substantial paramagnetic component attributed to iron-poor regions in the amorphous remainder was found.

Opis:: Amorphous and nanocrystalline FINEMET-type alloys with vanadium addition up to 7 at% were investigated by the MÖssbauer spectroscopy and magnetic methods. The outcomes evidence alterations in grain structure, although the main effect is related to the changes in intergranular phase. This induces diminution of mean hyperfine field, saturation induction and Curie temperature as well as the increase in coercivity.
