The results show that the onset temperature is 107.6K and the zero resistivity state occures at 94.8K with a width of about 2K for the sample of Ba_3Y_2Cu_5O_(5(3-z)). Diamagnetic susceptibility (Meissncr effect)was observed by magnetic susceptibility measurement, and confirmed with electrical resistance determination. The specimen consists mainly of hexagonal (or rhombohedral) ABO_3-type phase with lattice parameter of a=b=0.550nm, c=1.332nm and space group of R3c of R3m. The particles of oxide well connecte up each other, although quite a large number of pores exist. Zero resistance can be kept while up to 2A/cm~2 current passes through the sample. 收稿日期: 1987-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 朱乃平 江晓平 庞德兴 漆洪波 苏国跃 张泽 杨中进 俞华锋 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I3/250 1 Bednorz J G, Mueller K A.
