ABSTRACT

We investigate the effect of an impurity on the local static and dynamic behaviour of a crystal undergoing a displacive phase transition. It is shown that in mean-field approximation there may occur a freezing-out of local order driven by a soft local mode above the phase transition of the host. For a crystal containing a dilute impurity concentration, the impurity contribution to the static structure factor is calculated. The results are discussed in detail for the specific cases of a displacive and an Ising-type impurity. More... »
