The Concentration Fluctuation near Critical Temperature of Liquid Bi33.3Ga66.7 Alloy
The temperature dependence of resistivity of liquid Bi33.3Ga66.7 and Bi12Ga88 alloys was measured. Anomalous negative deviation of electrical resistivity of liquid alloys was found near critical temperature. Analysis in terms of the calculating equation for resistivity of liquid alloy suggests that, besides SCC(0), the pseudopotential matrix element and alloy composition still serve as crucial factors in scattering function. That is, concentration-concentration fluctuation in the long-wavelength is not necessarily induced an increase of resistivity of liquid alloy near critical temperature.
