Abstract
The Hall coefficients of liquid Se–Te alloys have been measured by an alternating current and a direct current magnetic field for operation temperature from their melting point to about 750°C. The signs are negative for liquid Te and liquid Se x Te 1- x , alloys with x =0.2, 0.3, 0.4 and 0.5. The absolute values of Hall coefficient for liquid Se–Te alloys exhibit the negative temperature coefficients and increase with increasing Se concentration. The Hall mobilities of these alloys have small negative temperature coefficients. The relationship between the Hall coefficient and the density of states at the Fermi level has been discussed on the basis of his formula given by Friedman.
