抄録

In order to control the dimensionality and the topology of the arrangement of magnetic Ru ions, NaCl-type lithium ruthenates have been investigated. Three types of lithium ruthenates, Li₃RuO₄, Li₂RuO₃, and cubic-Li_xRuO_1+x, were synthesized using a hydrothermal method. All of them have NaCl-type structure, but the arrangements of the cations, Li⁺ and Ru⁵⁺ (or Ru⁴⁺), differ from each other. Li₃RuO₄ with one-dimensional zigzag chains of Ru ions undergoes an antiferromagnetic transition at 66 K and exhibits an irreversibile magnetism below 32 K, where the zero-field-cooled susceptibility differs from the field-cooled susceptibility. Li₂RuO₃ with a two-dimensional honeycomb network of Ru ions demonstrates a paramagnetism almost independent of temperature. A novel ruthenate cubic-Li_xRuO_1+x, in which Ru and Li randomly occupy the cation sites of NaCl lattice, undergoes a spin-glass transition at 10 K.
