Dromions in (2+1) dimensional ferromagnetic spin chain with bilinear and biquadratic interactions

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.
