摘要

采用固相反应技术，在密封石英管内常压下制备了超导化合物样品。利用样品的电阻测量作为温度的函数，研究了化合物对电性能的影响。结果表明:相变增强，超导转变温度Tc提高。这可能是由于磁性杂质的减少或载流子的离域导致了导电CuO2平面中移动载流子密度的增强。

Effect of Preparation and Annealing Temperature on the Properties of (Hg,Tl)-2223 Superconductor

Samples of superconducting compounds were prepared by a solid-state reaction technique in a sealed quartz tube under normal pressure. The impact of the compound on the electrical properties has been studied using the electrical resistance measurements of the samples as a function of temperature. The obtained results appear that an enhancement in the phase formation, and the superconducting transition temperature Tc were improved. It may be due to the decreasing of the magnetic impurities or the delocalisation of carriers which resulted in the enhancement of the density of mobile carriers in the conducting CuO2 planes.
