Abstract
Reports acoustic-resonance measurements of the component s11 of the elastic compliance in SrTiO3 near its 105K phase transition. The observed critical singularity is stronger than that suggested by earlier measurements using pulse-echo techniques, and stronger than that predicted by the theory of ideal crystal critical behaviour. These results are indicative of a dynamic defect-controlled central-peak phenomenon.Keywords
