A method for making Tl-Ca-Ba-Cu-O superconductive materials as films are disclosed. After placing a Ca2Ba2Cu3O7 powder on to a suitable substrate, such as platinum or copper, the substrate and powder are rolled between two rollers until a desired thickness is achieved. The film can then be removed from the substrate. Thallium oxide is then evaporated on the film to make a superconductive film. The Tl2O3 can be evaporated in a furnace or vacuum. <IMAGE> |
