The magnetic susceptibilities of liquid SbTe, BiTe, SbSe, and BiSe systems are measured by the Faraday method using a torsion balance. The decrease in diamagnetic susceptibility at the melting point is relatively large in liquid Bi 2 Te 3 and Sb 2 Te 3 . On the other hand, it is considerably small in liquid Sb 2 Se 3 . This corresponds to the temperature change in the electrical conductivity reported previously. The value of susceptibility for liquid SbTe alloys is considerably different from the data measured by a previous author. It is clarified from the composition dependence of susceptibility that both liquid Te systems behave like metals rather than semiconductors in a wide range of composition. The composition dependence of susceptibilities in the liquid Se systems showes that in the Se‐rich region the short‐range bonding remains unchanged when melting, and these alloys take rapidly a metallic character with increasing metal content beyond the composition of Sb 2 Se 3 or Bi 2 Se 3 . These experimental results are discussed using the bond orbital approximation.
