摘要:

In this article we present a new method for the preparation of nonrandom Au‐YBa2Cu3O7−x(YBCO) composites. We describe the structural and the morphological properties of this novel system. Gold introduction into this system causes an increase in thecaxis value of the unit cell upon sintering at 950 °C. A systematic increase of the zero resistance transition temperature, up to 96 K as measured by a dc transport method, is observed upon the introduction of gold into the YBCO lattice. Introduction of gold above ≊3% by weight causes weakening of the intergranular links of the composite material.
