ELECTRICAL-RESISTIVITY OF LIQUID-QUENCHED AMORPHOUS-ALLOYS

Electrical resistivity measurements of amorphous (FexCo100-x)(83)B-17 alloys in the temperature range 40 K < T < 300 K have been obtained. W e observed from the analysis of the resistivity data that there is no s-d interaction or J(s-d) coupling. An empirical relationship for esti mating Theta(D) is suggested from the normalized electrical resistivit y data, which holds good both for theoretical and estimated Theta(D). For s-d interaction or J(s-d) coupling to occur in ferromagnetic amorp hous alloys, ordering of ferromagnetic domains, i.e. Heisenberg intera ction in a disordered matrix, would require temperatures of T less tha n or equal to Theta(D)/50 similar or equal to 0.02 Theta(D).
