Propagations of multiple solitons in a deformed ferrite

Abstract

In this work, we investigate the magnetic soliton profile and propagation properties of ultrashort waves in one-dimensional deformed ferrite. A generalized variable-coefficient (1+1)-dimensional ultrashort wave model is obtained by employing the multi-scale expansion method and short-wave approximation. Using numerical simulations, we examine the impact of multiple inhomogeneities on the transmission of magnetic solitons, which arise from local and periodic deformations. Our results indicate that the localized inhomogeneity alter the velocity of magnetic solitons, allowing for the manipulation of their acceleration or deceleration. Periodic type deformation inhomogeneities, on the other hand, provide the magnetic solitons with a period-like external potential that converts its transmission mode to a controlled oscillation.
