Studies of 3d Electrons and Hyperfine Interactions in Ordered and Disordered Fe₅₀Al₅₀ Alloys

Abstract:

The positron annihilation techniques and Mössbauer spectroscopy have been used to study the signals of 3d electrons and the hyperfine interactions in ordered and disorder Fe₅₀Al₅₀ alloys. The results show that the signals of 3d electrons of ordered Fe₅₀Al₅₀ alloy is very low. Mössbauer spectrum of ordered Fe₅₀Al₅₀ alloy shows a singlet, this alloy is paramagnetic. However, Mössbauer spectrum of Fe₅₀Al₅₀ powder being ball-milled for 70 h shows a discrete sextet, indicating a decrease in the long-range order within the Fe₅₀Al₅₀ powder being ball-milled for a long time.
