Magnetic properties of RSr2RuCu2O8+δ (R=Eu and Gd)

Abstract The non superconducting RSr 2 RuCu 2 O 8+ δ (R=Eu and Gd) compounds are magnetically ordered below T N =168 and 185 K, respectively. Magnetic susceptibility (ac and dc) studies indicate that the magnetic ordering is due to the Ru sublattice. The Gd sublattice in GdSr 2 RuCu 2 O 8 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 SrRuO 3 are compared.
