Abstract
A system with two interacting plasma fluxes for the deposition of high -temperature superconductor films is presented. This system prevents t he appearance of particles on a film surface, and permits one to obtai n YBa2Cu3O7-x films with the surface defect concentration as low as 10 (4) cm-2, a high critical temperature of 90 K, and a critical current density of 4X10(6) A/cm2 at 77 K. It is shown that high morphological quality films are obtained at a specific target-substrate distance.
