Abstract
ComparatiVe Fe-57 Mossbauer studies on amorphous Fe40Ni40B20 ribbon sp ecimens have been made. Using conventional and pulse super-ambient ann ealing procedures we investigated their relative effects on magnetic r elaxation and structural stability against crystallization. The result s are interpreted in terms of various structural relaxations and order ing mechanisms. The onset of crystallization is clearly detected at th e ribbon surfaces. Segregation of boron, which is a precursor to cryst allization in the present system, is smaller for pulse than for conven tional annealing procedures.
