| Abstract: | Measurements of the electrical resistivity as a function of temperature from 250 to 270 K for Au and f.c.c. phase AuGa alloys are presented. The linear dependence of the resistivity with temperature and previous results of the superconducting transition temperature of the alloys are used to obtain a value for Tc of pure Au. From these results a new method is introduced to estimate the Coulomb pseudopotential μ1 for gold. |
