✦ Synopsis

Laboratoire d'Etudes des Propri6tds Electroniques des Solides* C.N.R.S. BP166 -38042 Grenoble -France Magnetic properties and remanent magnetization have been measured on polycrystailine, textured, 1 I~ thick films of YBa2Cu307 prepared by RF reactive sputtering. Contributions to the remanent magnetization from intergrain and intragrain mechanisms can be separated. The temperature dependence of Mr is discussed in terms of granular superconductivity and thermally activated flux creep.

The strong negative electrostatic field applied to the surface of a high-To superconducting YBa2Cu3OT\_a thin film has been found to increase the transport critical current density (Jc) in the vicinity of T~. Ion implantation of oxygen increases Jc but, after implantation, a decrease of the critical
