Abstract

An isotope effect has been searched for in the high-T_c, superconductor YBa₂Cu₃0_{7 —b} through substitution of ¹⁸0 for ¹⁶O. No shift in the superconducting transition temperature T, is observed by electrical resistivity or magnetic susceptibility measurements. We discuss the implications of this result for mechanisms of superconductivity in the high-T, oxides.
