摘要：
Our research targets the study of the interaction and coupling between the two states, magnetic and superconducting, coexisting in the hybrid ruthenocuprates RuSr2GdCu2O8 (Ru-1212). While the magnetic phase arises from RuO2 layers, and the superconducting (SC) phase originates in the CuO2 planes, it is worth observing and investigating how the properties of these phases change under the substitution of Ru by Cu in this material. In order to study the effects of the annealing parameters and the substitution of Ru by Cu on the magnetic and SC properties of Ru-1212, five Cu-doped polycrystalline ceramic samples Ru1-xSr2GdCu2+xO8-delta ( x = 0 - 0.4) were synthesized and annealed under oxygen pressure at temperatures of 1039 and 1058 degrees C respectively.
