Bosonization and soliton in a crystal field anisotropic varying biquadratic ferromagnet

We investigate the nonlinear spin dynamics of a crystal field anisotropic continuum Heisenberg ferromagnetic spin chain with varying bilinear and biquadratic exchange interactions in the semiclassical limit. The spin excitations are found to be governed by solitons for specific relations connecting...

description We investigate the nonlinear spin dynamics of a crystal field anisotropic continuum Heisenberg ferromagnetic spin chain with varying bilinear and biquadratic exchange interactions in the semiclassical limit. The spin excitations are found to be governed by solitons for specific relations connecting exchange interaction and anisotropy. In the general case we construct perturbed solitons using a multiple scale perturbation analysis.
