Soliton Excitation in ferromagnetic Nanotubes with Higher Order Single Ion Anisotropy

Abstract

Dynamics of soliton in classical discrete Heisenberg ferromagnetic nanotubes (FN) with the effect of higher order single ion anisotropy was studied. The Hirota Bilinearization (HB) method was applied to the discrete nonlinear Schrodinger (DNLS) equation and obtains the soliton solution for FN system. The effects of exchange interaction and single ion anisotropy on soliton evolution along FN system were discussed through graphically.
