高温超导体化学的新进展去年我们介绍了高温超导体的发现以及由之而引起的世界性的超导热.当时达到的最高转变温度(T_c)为95K,得自“1-2-3”化合物YBa_2Cu_3O_7-x(X~0.1).一年来,世界各地的科学家以强烈的竞争姿态进行了深入的研究将转变温度提高到125K.这一进展和新型超导体的发现都足以令人乐观,但距离实现室温超导的目标仍然还很远. 在过去一年中,新型超导材料的合成与表征取得了很大的进步.但科学发展中往往出现
New Developments in High-Temperature Superconductor Chemistry Last year we introduced the discovery of high-temperature superconductors and the world-wide superconductivity caused by them. The maximum transition temperature (Tc) reached at that time was 95K and was obtained from “1-2-3” compound YBa 2 Cu 3 O 7 -x (X ~ 0.1). In the past year, scientists from all over the world conducted intensive research with a strong competitive stance to increase the transformation temperature to 125 K. Both this progress and the discovery of new superconductors are promising, but the distance to achieve room temperature The goal of superconductivity is still very far .In the past year, great progress has been made in the synthesis and characterization of novel superconducting materials. However, in the development of science,
