Transport électronique dans l’alliage liquide binaire Or–Argent

Abstract

Electronic transport in liquid binary alloys Gold-Silver

The electrical resistivity of the liquid alloy Gold-Silver was measured on the totality of the diagram of phase since the melting point until 1150°C. Our measurements, made in a quartz cell equipped with tungsten electrodes, were compared with those obtained by Roll and Motz using a technique without electrodes. The  technique that we used does not reproduce the anomalies observed by Roll and Motz in the curves of resistivity and its temperature coefficient as function of the concentration. The confrontation of our experimental results with the theory was made by using two types of  dephasing as well as the pseudopotential suggested by Idress et al. and used by Alam and Tomak.
