Description
Electronic-structure calculations, within the local spin density approximation (LSDA), are reported for PrBa2Cu3O7. Significant charge transfer from the Pr ions to both the CuO2 planes and the chains is found relative to YBa2Cu3O7. This supports hole depletion explanations for the insulating character of PrBa2Cu3O7. The LSDA electronic structure shows a prominent ''ridge'' Fermi surface analogous to that in YBa2Cu3O7, but broader. It is proposed that high-resolution positron measurements of this width may provide a useful test of hole depletion models
