RESISTIVITY OF LIQUID SR-BI AND SR-SB ALLOYS

Recently, measurements of the electrical resistivity, rho, of the liquid Sr-Bi and ST-Sb systems have been performed as a function of temperature for the entire concentration range. A very high and sharp resistivity maximum occurs at 60 at.% Sr for both systems, indicating that the mixture is semiconducting at this composition. Comparison with the Mg-Bi system is made and an attempt is made to give an explanation in terms of ionic ordering.
