Every new triangular lattice (TL) antiferromagnet attracts considerable attention since they usually display rich physics due to the inherent frustration and degenerate ground states stemming from the triangular structure. We propose to use WISH to confirm the proposed TL structure, determine the yet unknown magnetic structure and investigate the nature of the diffuse scattering in Li7RuO6. This experiment forms part of our wider work on other lithium ruthenates.
