Abstract : The presently claimed invention is direct to a process of making a noble metal and superconductor composite material and the noble metal and superconductor composite material itself. The present invention relates to a composite material film (and/or thin film) and a method of preparation wherein the composite material has a low critical current density and a high critical temperature. The invention particularly relates to a composite of a superconductor such as YBa2Cu3O(7-delta) (YBCO) or Bi2Sr2Ca2Cu3O(x) or Bi2Sr2Ca1Cu2O(x) (BSCCO) and one or more noble metals such as gold and/or silver upon a substrate, each material deposited at a desired thickness upon a substrate wherein magnetic vortices in the superconductor are easily moved.
