    • Abstract


      Mössbauer measurements have been performed on a number of metallic glasses. The temperature dependence of average hyperfine or internal magnetic fieldHeff(T) arises from long wavelength spin wave excitations in these glasses. Values ofB3/2 andC5/2 are in general much higher than those observed for crystalline ferromagnets indicating higher density of states for spin waves in amorphous ferromagnets.
