摘要	The crystal structure and superconducting properties of RuSr(2-x)Ba(x)GdCu(2)O(8) (0less than or equal toxless than or equal to0.1) have been investigated. X-ray powder diffraction (XRD) patterns show that the solid solution range is 0less than or equal toxless than or equal to0.1. The superconducting transition temperature was raised up to 35 K (zero) and 62 K (onset) for x=0.07, from 16 K (zero) and 45 K (onset) for x=0.0, and then T(C) decreases with x when x>0.07. Rietveld refinement for XRD data of RuSr(2-x)Ba(x)GdCu(2)O(8) show that the apical Cu-O(1) bond length increases with an increase of x, while the Ru-O(1) bond length decreases, This may account for the enhancement of the superconducting transition temperature.
