The onset critical temperatures of the present samples are 97.5, 97 and 95 K for the RE=Y, Sm and Nd, respectively. The first two values are the highest for the RE-Ba-Cu-O superconductors recorded to date. The RE3Ba5Cu8O18 samples crystallize in the orthorhombic system, with increased unit cell volume as Sm and Nd replace the element Y.eninfo:eu-repo/semantics/closedAccessCuprate SuperconductorsElectrical PropertiesSuperconductivityArticle10.1007/s10948-011-1176-7247209921022-s2.0-80054973110Q3WOS:000294535900010Q4
