The possibility of generating copper oxides with metallic properties was considered in Caen as early as 1979 on the basis of a mixed valence Cu(II)/Cu(III). Nevertheless, such an idea appeared at that time difficult to implement easily, since the only Cu(III) oxide which was known was the per

Thus, this chapter will focus above all on the chemical and crystallographic aspects of these substitutions and on their relationships with the superconducting properties, especially the evolution of the critical temperature.
