Experimental Constraints on Some Mechanisms for High-Temperature Superconductivity

Abstract

Since its discovery, many mechanisms have been suggested to explain the phenomenon of high-temperature superconductivity in oxides. We propose that experimental data, along with theoretical models, can place constraints on or exclude many of these mechanisms. The isotope shift-alpha, the transition temperature Tc, the ratio of the electronic-specific-heat jump to the normal-state specific heat Δ}C/γ Tc, and the superconducting gap ratio 2Δ}/kBTc are considered. We find limits on the applicability of solely phonon-based and combined phonon-electronic mechanisms.
