Some new results on amorphous Curie-temperature relaxation

Two reversible relaxation processes of similar activation energies can be separated in Cr-doped FeNiSiB metallic glasses by combined Curie-point and enthalpy-relaxation measurements. While one of the processes has a positive contribution to the activation-energy spectrum of the Curie-point, the other gives a negative contribution to it. The positive effect is associated with the ordering of Fe and Ni atoms in the FeNiSiB matrix while the negative effect is attributed to the Cr atoms.
