✦ Synopsis

We have measured the electron momentum density in both insulating PrBa 2 Cu 3 O 7Ϫd and superconducting YBa 2 Cu 3 O 7Ϫd : We find a remarkable difference in the anisotropy of the momentum density, even though LDA based calculations predict similar behaviour for both. Our results can be explained assuming Pr on Ba-site substitution disorder and we propose that this phenomenon is responsible for the observed effects.

We have used non-resonant microwave absorption to study c-axis YBazCuaO7\_6/PrBa2Cu307\_ 6 superlanices and compare the response to a film of similarly grown YBa2Cu307\_~ (YBCO). Near the respective transition temperatures, the response of the supedattice samples and the YBCO film have similar ampli
