This paper reports the superconducting properties of a solid-solution region in the Ba-Y-Gd-Cu-O system were investigated as a function of composition. Phase relations, the peritectic decomposition temperature, the superconducting onset temperature (T[sub c]), and the transport current density (J[sub c]) were measured. The highest T[sub c] and J[sub c] are observed along the line between the stoichiometric Ba[sub 2]YCu[sub 3]O[sub 6 + x] and Ba[sub 2]GdCu[sub 3]O[sub 6 + x] compositions.
