Abstract
Several oxides able to give rise to a high T{sub c} superconductivity have been studied. Samples were prepared in both series: La(Ba{sub 2-x}La{sub x}) Cu{sub 3}O{sub 7+y} and YBa{sub 2} (Cu{sub 3-x}Ag{sub x})O{sub 7-y}. The evolution of the resistance versus the composition has been studied on sintered samples. The results assess the importance of the experimental conditions of the synthesis. In the system La(Ba{sub 2-x}La{sub x})Cu{sub 3}O{sub 7+y} our results complete the work of Segre et al. and precise composition at which the superconductivity transition disappear for the profit of the semiconductive behaviour. The samples YBa{sub 2}(Cu{sub 3-x}Ag{sub x})O{sub 7-y} has for x = 0 electrical properties very dependent of the thermal treatment. Some characteristic data are shown. The partial substitution of Cu by Ag for x {ge} 1 enables to keep the superconducting behaviour.
