Query: Reply to: Comment by S.-L. Drechsler et al. (arXiv:1006.5070v2)   In a comment on arXiv:1006.5070v2, Drechsler et al. claim that the frustrated
ferromagnetic spin-1/2 chain LiCuVO4 should be described by a strong rather
than weak ferromagnetic nearest-neighbor interaction, in contradiction with
their previous work. Their comment is based on DMRG and ED calculations of the
magnetization curve and the magnetic excitations. We show that their parameters
are at odds with the magnetic susceptibility and the magnetic excitation
spectrum, once intensities are taken into account, and that the magnetization
curve cannot discriminate between largely different parameter sets within
experimental uncertainties. We further show that their new exact
diagonalization results support the validity of the RPA-approach, and strongly
reinforce our conclusion on the existence of a four-spinon continuum in
LiCuVO4, see Enderle et al., Phys. Rev. Lett. 104 (2010) 237207.
