Abstract
High-pressure studies have shown that crystals with small exhibit relaxational glasslike behavior rather than a static ferroelectric structural phase transition as previously thought. The results show a pressure-induced transition from frozen to relaxing impurity behavior and evidence for an off-center to on-center transition of the Nb ion at the site of the perovskite lattice.
