The Magnetic Susceptibilities of Liquid Na-TI, Na-Cd, Cu-Ga and Cu-Ge Systems

The magnetic susceptibilities of liquid Na-TI, Na-Cd, Cu-Ga and Cu-Ge systems were measured by the Faraday method over the whole range of composition. In the Na-TI alloys, a pronounced maximum of diamagnetism around the concentration of the NaTI phase (50 at% T1) found in the solid state almost disappeared on melting. These liquid alloys, however, showed a slight diamagnetic deviation from values interpolated using those of constituent elements. The magnetic susceptibilities of liquid Na-Cd alloys changed linearly with composition. In the liquid Cu-Ga and Cu-Ge alloys the diamagnetic peak was observed in the Cu rich region in the composition dependence of magnetic susceptibilities. It is considered that such a diamagnetic anomaly in liquid Cu alloys is caused by the formation of clusters some ionic character
