Abstract
Medium range order is analysed for Ni62Nb38 and Ni65B35 metallic glasses from the total and partial atomic pair correlation functions. A new fitting procedure is introduced to determine the extent of atomic correlations and the corresponding value for the structural disorder parameter (in a continuous form) as a function of the chosen window. The partial atomic pair correlation functions in the investigated medium range r-space behave differently and the medium range order is stronger in Ni62Nb38 than in Ni65B35.
