Lattice wave of magnetized spherical dust in radio-frequency sheath with negative ions is investigated.Thedispersion relation of two-dimensional hexagonal lattice horizontal wave and the influence of negative ions and magneticfield intensity on the wave are also investigated.The results show that for two-dimensional hexagonal horizontal latticewave,negative ions reduce the wave frequency at the range of long-wavelength,whereas raising the wave frequency atthe range of short-wavelength and magnetic field contributes to dropping the wave frequency a little.
