Amorphous glass with nominal chemical composition Fe₅₁Co₁₂Si₁₆B₈Mo₅P₈ was studied by combination of the Mössbauer spectroscopy and magnetic measurements in order to characterize magnetic and structural features. Temperature evolution of the Mössbauer spectra revealed presence of broad distribution of hyperfine magnetic field at lower temperatures which vanishes with increase of temperature. The Curie temperature estimated from the Mössbauer spectroscopy experiments is T_{C} ≈ 392 K. This value is in a good agreement with that obtained by magnetic measurements (T_{C}=397 K). The Mössbauer spectroscopy spectra of the sample annealed at 823 K revealed a presence of crystalline components. This temperature is notably lower than the expected temperature of the onset of crystallization observed by differential scanning calorimetry ( ≈ 835 K).
