一、高温超导材料分析讲解:高温超导材料表面上看是个物理问题,其实它与化学、材料等密切相关。因为高温超导材料主要是氧化物超导体系。以下的文献综述,可以帮助大家了解这一高新技术成果。文献综述:1908年,Karnerlingh Onnes 使氦液化,树立了超导研究方向的第一个里程碑。1911年 Onnes 首先发现水银在4K 时转变为超导态。随后人们在金属合金体系中为探索高 Tc 的超导新材料进行了大量的工作。1913年发现了 Pb 超导性(Tc=7.2K),1930年发现 Nb 超导性(Tc=9.2K),1954年发现 Nb_3Sn 超导性(Tc=18.1K),
First, the analysis of high temperature superconducting materials: High temperature superconducting materials on the surface is a physical problem, in fact, it is closely related with chemistry, materials and so on. Because high-temperature superconducting materials are mainly oxide superconducting systems. The following literature review, can help you understand this high-tech achievements. Literature Review: In 1908, Karnerlingh Onnes liquefied the helium, setting the first milestone in the field of superconductivity research. Onnes first discovered in 1911 that mercury turned to superconductivity at 4K. Then people in the metal alloy system to explore high-Tc superconducting new materials have done a lot of work. Pb superconductivity (Tc = 7.2K) was found in 1913, Nb superconductivity was found in 1930 (Tc = 9.2K), Nb_3Sn superconductivity (Tc = 18.1K) was found in 1954,
