Abstract
The magnetic susceptibilities of eight series of alloys: tin‐thallium, antimony‐thallium, thallium‐cadmium, zinc‐cadmium, lead‐antimony, tin‐antimony, cadmium‐antimony and zinc‐antimony have been investigated by Gouy's method. In three series,—antimony‐cadmium, antimony‐zinc and tin‐antimony an intermetallic compound is indicated by an abrupt change in the slope of the susceptibility concentration curve. The compounds thus indicated are SnSb, CdSb, and ZnSb with some evidence for the compound Sn2Tl. There is nearly a linear relation between the susceptibility and the concentration of one of the constituents where the constituents form simple heterogeneous mixtures—a result best illustrated in the zinc‐antimony series of alloys.
