Magnetic Susceptibility of Liquid Ag-As₂Se₃ System

The magnetic susceptibility of liquid Ag-As₂Se₃ system have been analyzed under the assumption that the paramagnetic susceptibility is attributable to the formation of dangling bonds. The diamagnetic susceptibility due to the ion core have been estimated in order to discuss the bonding nature and suggests that liquid Ag-As₂Se₃ system has a strong covalent bonding nature in As₂Se₃-rich region. The activation energy and the entropy of the formation of dangling bonds have also been estimated and these value decreases with increasing the concentration of Ag. These results are attributable to the destruction of As-Se network structure by the addition of Ag and the covalent bonding nature of overall network is gradually changed with composition.
