Reverse Monte Carlo and Voronoi analysis of the local atomic structure of metallic glasses Fe63Er2Mo14C15B6 and Fe75Y5B20

Using neutron diffraction data the analysis of local atomic structure of two metallic glasses has been performed. The analysis is based on the reverse Monte Carlo method in combination with the Voronoi tessellation technique. For the system Fe63Er2Mo14C15B6 the results are compared with the ab initio molecular dynamic modeling. The local structure and coordination numbers of Fe75Y5B20 to our knowledge are obtained for the first time and the validity of the results obtained is discussed.
