摘要: Anomalous lattice behavior near the onset of superconductivity has been observed by various experimental methods for a number high temperature superconducting oxides. However, some other probes do not detect such an anomaly. Moreover, its relevance to mechanism controversial. Based upon our pulsed neutron scattering studies we suggest that this confusing state affairs is due primarily highly localized and dynamic nature distortion which produces The magnitude too large be dismissed merely as consequence transition. We distortions represent polarons or bi-polarons, they play crucial role in superconductivity.
