Partial pair correlation functions of La1−x(AlGaAu)x metallic glasses from x-ray diffraction data

X-ray diffraction studies of La_1?xAl_x, La_1?x(Al_0.5Ga_0.5x, La_1?xGa_x and La_1?xAu_x metallic glasses have been performed for x = 0.20, 0.24 and 0.28. Similarities in the radial distribution functions for these materials as well as other data suggest that these alloys are isostructural. Experimental data from different alloys have therefore been used to separate the three different pair distribution functions, which are then compared to dense random packing models and data for other metallic glasses.
