Abstract

Recent site-selective oxygen isotope effect measurements in YBa2Cu3O7 yield a small inverse isotope effect for 18O substitution in the plane sites. This result is consistent with an anharmonic phonon model of superconductivity, which in turn yields predictions for the site-selective isotope effects in lower-Tc compounds such as YBa2-xLaxCu3O7 and YBa2-xSrxO7.
