Abstract: Abstract The existence of localized spin excitations and spin deviations along the site in an inhomogenity induced one-dimensional antiferromagnet (AFM) with Dzyaloshinski-Moriya (D-M) interaction has been studied. A discrete set of coupled nonlinear partial differential equations that governs the dynamics is arrived. The quantum localised spin modes are calculated in the presence of different inhomogenities. The multiple-scale method is employed and multi wave soliton solutions are constructed and depicted graphically. Graphical abstract
