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...
