We study the effect of crystal-field anisotropy on the dispersion relations of mixed-spin (S, s) alternating chains by using the interacting spin-wave theory and the density-matrix renormalization group algorithm. For the easy-plane anisotropy case we find that the spin-wave results fail to describe
