Effects of point defects and composition on structural phase transition. 1989-90 technical report.

摘要

During the first three years of this project, we have concentrated our effort on three systems: KTa(sub 1(minus)x)Nb(sub x)O(sub 3), KZnF(sub 3):Li and KMnF(sub 3):Li. The initial goals of the study were (1) to develop the necessary experimental capabilities, (2) to identify the nature of the defects, (3) to characterize the effect of these defects on the phase transition. These goals have been successfully reached and we now propose to pursue the present research along three lines.
