摘要：
Electronic and magnetic properties of RuSr2GdCu2O8 have been investigated by resistivity, magnetization and NMR measurements. Magnetic order (TC=133 K) and superconducting transition (TS(onset) ∼52 K) have been confirmed in RuSr2GdCu2O8. We observed two kinds of Ru-NMR signals (the hyperfine fields of 101Ru are 590 kOe and ∼290 kOe), suggesting a possible charge segregation of Ru4+(S=1) and Ru5+(S=3/2) in the RuO2 layers. Holes can be inherently doped in the CuO2 layers from the (Ru4+, Ru5+)O2 layers, and the superconductivity can occur under weak magnetic interactions between Ru and Cu spins in RuSr2GdCu2O8.
