Simulations of Experimentally Detected Ambient Skyrmions in Symmetric Synthetic Antiferromagnetic Multilayers

Magnetic skyrmions are topological solitons consisting of non-collinear spin textures that display promising properties for spintronic information storage and logic devices. A type of system that has been proposed to host 2D skyrmions in room-temperature and zero magnetic field conditions, is the synthetic antiferromagnetic multilayer, composed of ferromagnetic layers that exhibit antiparallel RKKY coupling mediated by a non-magnetic spacer. In this work, we performed micromagnetic simulations to complement an experimental investigation about ambient skyrmions in Pt/Co/Ru/Co/Pt multilayers, assessing their magnetization reversal properties and coupled skyrmion stability.
