Abstract
The noise characteristics of YBa2Cu3O7-x films prepared by the laser ablati on technique on SrTiO3 substrates were studied. The epitaxial YBCO films po ssess a perfect structure and are characterized by a narrow superconducting transition, strong pinning, and a very small flicker noise. In the normal state, the 1/f noise increases with the dislocation density. The minimum no ise level with a Hooge parameter of (2-3) x 10(-6) was observed at a disc l ocation density of 8-12 mum(-2).
