Abstract

The temperature dependence of the electric field gradient (EFG) at111Cd impurities in yttrium metal has been investigated between 77 K and 500 K by time differential perturbed angular correlation measurements. The EFG decreases with increasing temperature. This decrease can be fully explained by the lattice expansion. The value of the EFG at 293 K

$$\left| {V_{zz} (^{111} Cd\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{Y} )} \right| = 0.83(2) \cdot 10^{17} V/cm^2 $$

is consistent with the correlation between ionic and electronic EFG proposed by Raghavan et al.
