Abstract:

We examine the isotope effect in copper-oxygen high-T-c superconductors using the model of polar Jahn-Teller centers, a variant of the local-boson model. The isotope-effect exponents for oxygen and copper depend on the structure of Jahn-Teller centers and its variation due to boson motion. A number of YBa2Cu3O7-delta-based compounds are used to illustrate the feasibility of quantitatively describing the experimentally observed values of alpha(Cu) and alpha(O) and their relationship to T-c.
