Abstract

Skyrmions are considered as topologically protected magnetic textures; they are covering a large area of applications. In this work, we studied using micromagnetic simulations the emergence of skyrmions in a nanodisk stacked in a FM/NM/FM multilayer system. We show how the skyrmion is formed through the antiferromagnetic interlayer exchange coupling (IEC). We also show the impact of the IEC on skyrmion size in both layers. We try as a conclusion to identify the range of IEC where skyrmions could exist in such systems.
