Abstract

The invention concerns a copper of mixed valency derived from the structure of perovskite and of formula: Pb1-x Alt2+y+x Tr1-z Et2 O7-ε with z greater than or equal to 0, lesser than or equal to 0.6, preferably greater than 0.1; x greater than or equal to 0 and lesser than 0.9, preferably greater than 0.1; y greater than or equal to 0 and lesser than or equal to 1, preferably greater than 0.1 and lesser than 0.9; with epsilon varying between -0.1 and 2/3 preferably 1/2; Alt represents the alkaline-earths with the exception of magnesium, Tr represents the rare-earths, preferably yttrium, lanthanum and the lanthanides; and Et represents the transition elements from d5 to d10, copper representing at least seven out of eight atoms of said transition elements. Application: electrical and electronic industry.
