摘要：

Well developed single crystals of the mercury compound HgBa2Ca2Cu3O8+d have been obtained in single step synthesis under normal pressure conditions. Samples in the submillimeter range give a sizeable diamagnetic signal which allowed a systematic study of the magnetization anisotropy both before and after annealing in oxygen. After annealing, single crystals displayed a sharp superconducting transition temperature with an onset at 135 K. The direct determination by X-rays of the annealed crystal structure was carried out in addition to the analysis of the changes in the diffraction spectrum associated with the annealing process and the improvement of the transition temperature.
