摘要：

We have investigated the magnetic and the superconducting properties of the hybrid ruthenate-cuprate compound RuSr2GdCu2O8 by means of zero-field muon-spin rotation (ZF-mu SR) and de magnetization measurements. The dc-magnetization data established that this material exhibits ferromagnetic order of the Ru moments [mu(Ru)approximate to 1 mu(B)] below T-C = 133 K and becomes superconducting at a much lower temperature T-c = 16 K. The ZF-mu SR experiments indicate that the ferromagnetic phase is homogeneous on a microscopic scale and accounts for most of the sample volume. They also suggest that the magnetic order is not significantly modified at the onset of superconductivity. [S0163-1829(99)07321-X].
