Abstract
By implantation of181Hf ions radiation damage is produced in platinum. Subsequent annealing of the samples leads to the trapping of a unique defect at the probe atoms. The temperature dependence of the resulting electric field gradient eq(T) is measured by use of the TDPAC-method. Assuming a relation eq(T)=eq(0)·(1−B·T 3/2) one findsB=(1.9±0.7)×10−6 K−3/2. This low value is of the same magnitude as the corresponding values for111Cd in various locally distorted cubic metals.
