Abstract
Pure platinum foils were quenched from high temperatures to liquid helium temperature in order to freeze in a high vacancy concentration. The lattice parameter change Delta a/a and electrical resistivity change Delta rho were measured simultaneously on the same sample. The defect specific ratio of both property changes was found to be eta v=(( Delta a/a) Delta rho )VPt=-(0.24+or-0.03) 103 ( Omega cm)-1. A characteristic specific volume change ( Delta V/ Omega VPt=-(0.42+or-0.06) due to vacancies in platinum was obtained.Keywords
