摘要：

The substitution of Y by Zr in the YBa2Cu3O7-delta has been investigated. A structural study has been performed in samples with nominal composition Y1-xZrxBa2Cu3O7-delta following different preparation procedures by means of X-ray powder diffraction and Zr K-edge EXAFS spectroscopy. This work demonstrates that Zr does not replace Y in the YBa2Cu3O7-delta structure, and a multiphase system is obtained. Magnetic and electrical measurements performed over these samples are in agreement with this structural description.
