Özet

This paper presents the synthesis and characterization of the new superconducting compounds with nominal composition, RE3Ba5Cu8O18, RE=Y, Sm and Nd. 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.
