Abstract
We have seen, by Mössbauer spectroscopy, magnetization and resistivity, changes on the physical properties of the a- Fe20Ni60B20 alloy induced by thermal relaxation, notedly increases in Tc and resistivity. These changes can be explained by modifications of the chemical short range order around Fe favouring the formation of Fe-Ni pairs.
