Three series of oxides Ba,Y, \_,CaXCu3\_,FeX0,, tetragonal and orthorhombic, and Ba,Y I \_XCaXCu,\_,FeXO, tetragonal, have been synthesized by successive appropriate thermal treatments under oxygen and argon, for x=0.09,0.12,0.15,0.24. The structure of these different forms has been determined by ne
