A liquid-electrolyte voltammetric probe of superconducting oxocuprates through the transition temperature Tc

Abstract

New free-solue ferrocene/ferricinium electrochemistry, in liquid electrolyte on Tl-containing oxocuprate superconducting electrodes studied at several temperatures above and below T_c shows no discontinuties or abnormalities at the transition, in contrast with solid-electrolyte behaviour but possible in accord with theoretical predictions regarding virbronic interactions or reroganisation barriers.
