The Isotope Effect in Superconductors

Superconductivity 2023-07-12 v1

Abstract

We review some aspects of the isotope effect (IE) in superconductors. Our focus is on the influence of factors not related to the pairing mechanism. After summarizing the main results obtained for conventional superconductors, we review the effect of magnetic impurities, the proximity effect and non-adiabaticity on the value of the isotope coefficient (IC). We discuss the isotope effect of TcT_c and of the penetration depth δ\delta. The theory is applied to conventional and high-TcT_c superconductors. Experimental results obtained for YBa2_2Cu3_3O7δ_{7-\delta} related materials (Zn and Pr-substituted as well as oxygen-depleted systems) and for La2x_{2-x}Srx_xCuO4_4 are discussed.
