The electrical resistivities and the magnetic susceptibilities of liquid tellurium alloys containing the rare earth solutes have been measured from the melting point to about 900°C. The temperature-independent susceptibilities of light rare earth solutes are considerably larger than the theoretical values. The effective magneton numbers of light rare earth solutes are smaller than the theoretical values. The 4f electrons of light rare earth solutes interact with the conduction electrons. The additional resistivities do not vary much from one rare earth to another. The increments of the resistivity caused by the rare earth solutes are interpreted as a decrease in the density of states at Fermi level EF.
