Abstract :
Very recently, an important class of magnetic solitons called magnetic skyrmions has been widely studied [1,2]. The stability of these topological defects has been analyzed in the presence of intrinsic dissipation both as a function of Dzyaloshinskii-Moriya interaction (DMI) and as a function of a spin-polarized current (SPC).
