Abstract

Starting from high quality Nd_1.85Ce_0.15CuO₄ polycrystalline samples with a T_c of 24K, we have exchanged ∼85% of ¹⁶O by ¹⁸O. The magnetically measured T_c was found to change by less than 0.1K, equivalent to an oxygen-isotope exponent ⁰α≤0.05. Thus, the isotope effect is small for all classes of cuprate superconductors when T_c is optimized, irrespective of CuO coordination and conduction type.
