摘要：
Introducing the coherent state ansatz and the time-dependent variational principle, two partial differential equations of motion are obtained from the Hamiltonian. Employing the method of multiple scales, these equations are reduced into the envelope function equation and the amplitude function satisfying a nonlinear Schrodinger equation is found. The periodic wave solution and analysis of its stability in the antiferromagnet Ni(C2H8N2)(2)NO2ClO4 is derived.
