Investigation of amorphous and crystalline Sc3Fe alloys

Amorphous Sc3Fe alloy has been prepared by splat-cooling with levitation melting. The quadrupole splitting distributions for Sc3Fe were determined from Mossbauer spectra: the zero-field distribution has a Gaussian form. The analysis of Mossbauer spectra taken in applied magnetic field show that both positive and negative signs of principal component (Vz2) of electrical field gradients (EFG) are present. The crystallization process has also been investigated. Heat treatment of the amorphous alloys causes crystallization first into a metastable, and then into the stable phase.
