Isotope Effect Study of κ-(BEDT-TTF)2Cu(NCS)2: Labeling in the Anion

Abstract Isotopic labeling in the anion of the organic superconductor κ-(BEDT-TTF)2Cu(NCS)2, with 13C and 15N isotopes in the thiocyanate groups, has been carried out. This labeling does not lead to an isotope effect on the superconducting transition temperature (T c).
