The temperature-dependent behavior of the Yb3+ and Ru5+ moments suggests that the 4d electrons of Ru5+ play a dominating role in stabilizing the long-range-ordered magnetic ground state in the double-perovskite Sr2YbRuO6 whereas only the Yb3+ moments show an arrest at T-N2. The observed magnetic structure and the presence of a ferromagnetic interaction between Ru and Yb ions are explained with use of the Goodenough-Kanamori-Anderson rules.
