Abstracts

EN

Static and dynamical behaviour of amorphous ferromagnets FeNiSiB was investigated by the Mössbauer spectroscopy and magnetostatic methods below and above T_{C}. The distributions of hyperfine magnetic field in the ferromagnetic phase and quadrupole splitting in the paramagnetic one were extracted by means of the constrained Hesse-Rübartch method. The static critical exponents were determined using the power laws and the Kouvel-Fisher method. The results of the Mössbauer investigations were compared with those obtained by magnetic measurements.
