Abstract: | The hyperfine magnetic field at57Fe in the ferromagnetic Laves compounds Hf(Fe1?x Co x )2 was measured by the Mössbauer effect method. The substitution of Fe atoms by Co atoms induces a gradual change ofB hf(Fe) and a decrease in the magnetic moment values in Fe?Co sublattice. The perturbed angular correlation measurements of181Ta were carried out forX=0,X=0.1,X=0.55 at 300 K, andX=0.4 atT=400°C. An abrupt change ofB hf (Ta) in 0<X<0.1 was observed. |
