We have investigated the high field magnetisation of the frustrated onedimensional compound LiCuVO4. In zero field, LiCuVO4 undergoes long rangeantiferromagnetic order at T_{N} ~ 2.5 K with a broad short range Schottky typeanomaly due to one dimensional correlations in the specific heat at 32 K.Application of a magnetic field induces a rich phase diagram. An anomaly in thederivative of the magnetisation with respect to the applied magnetic field isseen at ~ 7.5 T with H ll c in the long range order phase. We investigated thisin terms of a first experimental evidence of a middle field cusp singularity(MFCS). Our numerical DMRG results show that in the parameter range of LiCuVO4as deduced by inelastic neutron scattering (INS), there exists no MFCS. Theanomaly in the derivative of the magnetisation at ~ 7.5 T is therfore assignedto a change in the spin structure from the ab plane helix seen in zero fieldneutron diffraction.Comment: 7 pages, 4 figures, to appear as a special edition in J. Phys. Cond.  Mat as part of the proceedings of the HFM2006 conference in Osaka, Japa
