摘要	Employing the Holstein-Primakoff transformation, first the spin-Hamiltonian is transformed into a boson Hamiltonian. Then, using a coherent state ansatz, a time-dependent variational principle, and the continuum approximation, two nonlinear coupled equations are obtained. Finally, these equations of motion, which describe the dynamics of the system, are reduced to one nonlinear Schrodinger equation with localized envelope soliton solutions. Introducing the inverse scattering transformation, single-, two-, and N-soliton solutions are obtained and the solitary excitations in the antiferromagnet KCuF3 are investigated.
