摘要

We study the dynamics of (2 + 1) dimensional ferromagnetic spin chain with bilinear and biquadratic interactions by using Holstein-Primakoff (HP) representation and the coherent state ansatz. The dynamical equations of motion are obtained by using long wavelength approximation. The sine-cosine function method is used to study the complete nonlinear excitation and the effect of the different types of interactions is investigated graphically.
