BOND CHARACTER IN LIQUID ALLOYS FROM MAGNETIC-SUSCEPTIBILITY

A model of assumed reactions mu-A+nu-B reversible A(mu)B(nu) has proven very useful in liquid alloys with strong A-B bonding, where it describes thermodynamics (DELTA-H, etc.), Knight shifts and quadrupolar relaxation. It is here applied to discuss the contributions to the magnetic susceptibility, made by the right-hand side state of the reaction (A(mu)B(nu)). By combining with a description of the susceptibility as a function of the degree of covalency in crystalline compounds, an estimate of that degree for the A-B bonds in several liquid-metal-Te alloys is derived. Thus it becomes possible to place them on a bond character chart.
