Abstract

A novel metallic compound with a spin-1/2 triangular lattice is reported. It is a silveroxonickelate Ag₂NiO₂ containing a NiO ₂ layer which possesses a spin-1/2 triangular lattice with twofold spin and twofold orbital degeneracy. It is found that a structural transition takes place at T_s = 260 K, which may be related to orbital ordering, and long-range antiferromagnetic order sets in below T_N = 54 K.
