FIG. 2.

Relaxation frequency as a function of in (filled stars), (empty stars), and in (empty squares) and in (empty circles). The solid lines are least-square fit to Eq. (6) with relaxation attributed to the off-center ions or to polaronlike defects or and to . The best-fit parameters are presented in Table I.
