| Popis: | Based on X-ray and DTA analyses, a systematic study of the synthetic conditions, the structure, the phase formation processes and the superconducting properties of the high- T c superconductor Pb 2 Sr 2 Y 1− x Ca x Cu 3 O 8+δ ( x T c superconductor is very subtle and sensitive to the preparative atmosphere and temperature, suggesting that not only the oxygen stoichiometry but also other factors such as oxygen ordering or lone pair formation should play an important role for high- T c superconductivity in this system. |
