Abstract

In 1987, M. K. Wu and Paul Chu discovered Y 1.2 Ba 0.8 CuO 4 (YBCO) with critical temperature (T c ) of 93 K. It has significantly lowered the cost of cooling of a material up to the point where superconductivity set in. Utilizing the cost reduction of attaining superconductivity and the vast amount of research to understand characteristics of high temperature oxide superconducting materials, there has been effort to use a high temperature superconductor as a coated conductor. It is important to characterize the materials precisely for stable performance before commercializing. We used polarized Raman scattering spectroscopy to study structural and stoichiometric information regarding YBa 2 Cu 3 O 7-x , GdYBa 2 Cu 3 O 7-x , and GdBa 2 Cu 3 O 7-x produced by three leading groups of producing commercial grade high temperature superconductor coated conductors American Superconductor Corporation, Superpower, and SuNAM.

用偏振拉曼光谱研究商业级mba2cu3o7 -x (M = Y和/或Gd)涂层导体的局部结构

1987年，M. K. Wu和Paul Chu发现临界温度为93 K的y1.2 Ba 0.8 CuO 4 (YBCO)。它大大降低了材料冷却到超导的成本。利用获得超导性的成本降低和对高温氧化物超导材料特性的大量研究，人们一直在努力使用高温超导体作为涂层导体。在商业化之前，对材料进行精确的表征以获得稳定的性能是非常重要的。我们利用偏振拉曼散射光谱研究了美国超导公司、超级大国和SuNAM三个生产商业级高温超导涂层导体的领先团队生产的YBa 2 Cu 3 O 7-x、GdYBa 2 Cu 3 O 7-x和GdBa 2 Cu 3 O 7-x的结构和化学计量信息。
