    • Abstract

       

      Magnetic metallic glass Fe39Ni39Mo4Si6B12 has been studied by the57Fe Mössbauer spectroscopy. Mössbauer spectra consist of broad and overlapping six-line pattern below the Curie temperature. The Curie and crystallization temperatures of this metallic glass have been determined to be 575 ± 3 K and 725 ± 3 K, respectively. The hyperfine magnetic field at room temperature is approximately 225 kOe. The reduced hyperfine fields of this sample decrease much faster than that observed for other iron-rich metallic glasses like Fe40Ni40B20, Fe80B20 etc. This behaviour is attributed to the presence of molybdenum atoms in the sample.
