Abstract
A method of preparing a substrate with a view to depositing a thin layer of a superconductive material thereon, wherein an operation is performed of depositing on the substrate an intermediate material having the property of having a crystal lattice constant that is a function of the percentage of a doping element, the depositing operation being initiated with a concentration of the doping element such that the lattice constant of the intermediate material is equal to or as close as possible to the lattice constant of the substrate, the proportion of the doping element being continuously varied during the depositing operation to a proportion of the doping element such that the lattice constant of the intermediate material is equal to or as close as possible to the lattice constant of the superconductive material.
