Effect of Varying Dzyaloshinskii—Moriya Interaction on the Bistable Nano-Scale Soliton Switching

The effect of Dzyaloshinskii—Moriya (D-M) interaction on the bistable nano-scale soliton switching offers the possiblity of developing a new innovative approach for data storage technology. The dynamics of Heisenberg ferromagnetic spin system is expressed in terms of generalized inhomogeneous higher order nonlinear Schrödinger (NLS) equation. The bistable soliton switching in the ferromagnetic medium is established by solving the associated coupled evolution equations for amplitude and velocity of the soliton using the fourth order Runge—Kutta method numerically.
