| Popis: |
The effect of metal doping on the transition temperature (Tc) of Bi1.9−xPbxSb0.1Sr2Ca2Cu3Oy (0.05≤×≤0.40) was investigated. Doping with 10 atom% Pb produced a sample with maximum Tc in the series. The oxidation state of Cu and oxygen stoichiometry in these cuprates were determined by iodometry and fast neutron activation analysis (FNAA). Excellent agreement in oxygen data derived from iodometry and FNAA were observed. An apparent relationship between the average oxidation state of Cu and Tc values of these materials were observed. |
