Mixed Valence Copper Oxides, High Tc Superconductors : Structural Study and Electron Transport Properties
Abstract Perhaps more than hundred papers have been published about the subject of mixed valence copper oxides related to the pervoskite since the first signs of superconductivity shown by Müller and Bednorz in the system Ba-La-Cu-O1, 2. The rush in this area of research results from the fact that most of the physicists were convinced that the critical temperature of 23.3K observed for Nb3Ge was a limit difficult to overtop Infact a great mumber of those oxides were synthesized and studied for the first time in Caen from 1980 to 1986. In the first part of the present paper synthesis, crystal chemistry and electron transport properties of the oxides A-La-Cu-O (A = Ba, Sr, Ca) carried out in Caen are reported. The second part of this study deals with our recent studies of the second generation of high Tc superconductors, YBa2Cu3O7±∈.
