We report the synthesis and characterization of RuSr2GdCu2O8-La0.67Sr0.33MnO3 superconducting-magnetic composites with 0 to 50 wt% of La0.67Sr0.33MnO3 in the composites. Systematic measurements of magnetization as a function of applied magnetic field at up 5 kOe were performed at temperature regimes below the Curie temperature (TC) of La0.67Sr0.33MnO3 but above the Néel temperature (TN) of RuSr2GdCu2O8; below TN of RuSr2GdCu2O8 but above the superconducting critical temperature (TSC) of RuSr2GdCu2O8; and below TSC of RuSr2GdCu2O8. Our results reveal the ferromagnetic character of the composites at the temperature regime TN < T < TC. Exchange bias effect was observed for weak applied fields (H <1.5 kOe) at the temperature regime TSC < T< TN. At the superconducting temperature regime (T<TSC) weaker exchange bias is observed for low magnetic fields (H < 0.6 kOe). For strong magnetic fields (H> 2 kOe) the ferromagnetic character of the system is recovered.
