| 摘 要： | 在LnBa2Cu3O7-y单晶上的一系列实验事实表明:体内存在的结构不完整性和组成不均匀性都对其正常态电阻率、正常-超导转变行为、超导临界温度,以及临界电流等产生重要影响。作者认为:与单相多晶LnBa2Cu3O7-y样品相类似,非理想的单晶体也存在着超导玻璃态效应。

| Abstract: | A series of experimental facts for Ln Ba2Cu3O7-y single crystals indicate that imperfect structure and non-uniformity composition in samples have an important effect on their normal state resistivity, normal-superconductive transition behavior, Tc and critical current and so forth. We think that in imperfect single crystals, there also exist superconductive glass state effects, similar to single phase polycrystal LnBa2Cu3O7-y samples. |
