摘要：

The non superconducting RSr2RuCu2O8+delta (R = Eu and Gd) compounds are magnetically ordered below T-N = 168 and 185 K, respectively. Magnetic susceptibility (ac and de) studies indicate that the magnetic ordering is due to the Ru sublattice. The Gd sublattice in GdSr2RuCu2O8 is antiferromagnetically ordered at 2.8 K. Irreversibility phenomena and magnetic anomalies, observed at low magnetic fields, originate from antisymmetric exchange coupling of the Dzyaloshinsky-Moria type, and from spin reorientation of the Ru moments. The magnetic behavior of this system and that of the well-known itinerant ferromagnet SrRuO3 are compared. (C) 1999 Elsevier B.V.Science. All rights reserved.
