abstract = {The structure of Ge$_{22}$Ga$_3$Sb$_{10}$S$_{65}$ and
Ge$_{15}$Ga$_{10}$Sb$_{10}$S$_{65}$ glasses was investigated
by neutron diffraction (ND), X-ray diffraction (XRD), and
extended X-ray absorption fine structure (EXAFS)
measurements at the Ge, Ga and Sb K-edges. Experimental data
sets were fitted simultaneously in the framework of the
reverse Monte Carlo (RMC) simulation technique. Short range
order parameters were determined from the obtained
large-scale configurations. It was found that the
coordination numbers of Ge, Sb and S are around the values
predicted by the Mott-rule (4, 3 and 2, respectively). The
Ga atoms have on average 4 nearest neighbors. The structure
of these stoichiometric glasses can be described by the
chemically ordered network model: Ge-S, Ga-S and Sb-S bonds
are the most important. Long Sb-S distances (0.3–0.4 Å
higher than the usual covalent bond lengths) are observed,
suggesting that Sb atoms can be found in various local
environments.},
