A new method to determine of the nearest neighbor (1NN) coordination number
s for binary disordered alloys is proposed. The method is reduced to the so
lution of the system of linear algebraic equations for the partial coordina
tion numbers. As input data we use 1NN partial interatomic distances obtain
ed independently for each EXAFS spectrum in binary alloy and the Debye-Wall
er factors.
Coordination numbers End interatomic distances for 75 and 80 at.% Ni-Mn all
oys in ordered and disordered states are presented.
