A series of amorphous alloys of Fe80B20, with a constant amount of transition metal substitution and the nominal composition Fe75TM5B20, have been obtained by the “melt-spinning” technique. Differential scanning calorimetry, resistivity, small angle x-ray scattering measurements, and Mössbauer spectroscopy have been utilized to study the substitution-induced modification of the behavior, in both the amorphous and annealed states, of the temperature and enthalpy of crystallization, the activation energy for crystallization, the electrical resistivity, the local magnetic and electronic properties, and the structural homogeneity. The effects of substitution on the electronic structure and hyperfine field at the iron atoms are also discussed.
