Abstract

An oxygen isotope effect is observed by a measurement of the resistivity when ¹⁶O is infstituted for ¹⁸O in the YBa₂Cu₃O_7-δ compound. The superconducting transition temperature T _c is lowered by 0.4 K upon infstitution. The results suggest that the phonon related to oxygen in the two-dimensional CuO₂ plane contributes to the mechanism of high-T _c superconductivity. When ⁶³Cu is infstituted for ⁶⁵Cu, no appreciable isotope effect is observed.
