<p>The object of the present invention is a superconductive material formed as a film comprised of monomolecular layers (2, 3, 4, 5) stacked on a substrate (1), wherein said film includes at least one first set (R) of layers which form a reservoir of electrical charges, and a second set (S) of layers which form a superconductive cell and which contain a number of superconductive copper oxide layers (4), separated from each other by spacing layers (5), the reservoir and the superconductive cell being adjacent in the layer stack. According to the invention, n is an integer of at least 4, and the spacing layers are of chemical formula Ca1-xMx and are free of strontium, wherein x is a real number between 0 and 0.2, M is a component with an ionic radius close to that of the Ca2+ ion, and the spacing layers may be complete or not.</p> |
