Abstract

The quadrupole interaction of ${}^{111}{Cd}$ in undoped (congruent) and Mg-doped ${LiNbO}_{3}$ single crystals has been studied using the perturbed angular correlation technique after implantation of ${}^{111}{In}$ and ${}^{111 m}{Cd}$ . A stepwise-annealing procedure shows the lattice to be fully reconstructed at 773 K. Our results show that both In and Cd are in the Li position. Mg doping at 6 mol % does not have any effect on the lattice location of these impurities in ${LiNbO}_{3}$ .
