| Static and dynamical behaviour of amorphous ferromagnets FeNiSiB was investigated by the Mössbauer spectroscopy and magnetostatic methods below and above TC. 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. |
