Abstract

The phase transition in the compound LiVGe₂O₆ has been proposed as a unique example of a spin-Peierls transition in an S = 1 antiferromagnetic chain. We report neutron- and x-ray-diffraction measurements of LiVGe₂O₆ above and below the phase transition at T = 24 K. No evidence is seen for any structural distortion associated with the transition. The neutron results indicate that the low-temperature state is antiferromagnetic, driven by ferromagnetic interchain couplings.
