Resum
The high Tc superconducting oxides YBa2Cu Fe 0 with x=O.O75, 0.1, 0.2 and 0.45 are studied by electrical resistivity, thermoelectric power and infrared absorption spectroscopy, in order to have some light on the superconducting trans port mechanism. The transition temperature Tc lowers gradually increasing x, and the metallic and superconductor features are degraded with x. Thermg electric power S is appeared to be very sensitive to the changes on samples. S is always positive abg ve Tc, its val...
