摘要：

Anomalies in vibrational spectra measured by neutron and Raman scattering and spatial inhomogeneities in -1618O exchange lead to a two-region micromorphological model of YBCO. This model explains why among single-phase high-temperature superconductors only YBCO exhibits a nearly zero isotope effect. This small isotope effect has been used as the justification for many exotic nonphonon models of high-temperature superconductivity, but the present discussion shows that such models are unnecessary. © 1990 The American Physical Society.
