Ln3Ni2RuO9 (Ln?=?La, Nd) oxides (prepared by a solid state metathesis route) adopt a monoclinic (P21/n) A2BB'O6 double perovskite structure wherein the two independent octahedral 2c and 2d sites are occupied by Ni2+ and (Ni2+1/3Ru5+2/3) cations, respectively. In contrast to the expected ferromagnetic behavior, Ln3Ni2RuO9 oxides show a spin-glass behavior without long range magnetic order down to 2?K. These results reveal the importance of competing nearest neighbor (NN), next nearest neighbor (NNN) and third nearest neighbor (third NN) interactions between the magnetic Ni2+ and Ru5+ ions in the partially ordered double perovskite structure that conspire to thwart the expected ferromagnetic order in these materials. | |
