Lorentz TEM investigation of chiral spin textures and Néel Skyrmions in asymmetric [Pt/(Co/Ni)${}_M$/Ir]${}_N$ multi-layer thin films

Maxwell Li, Derek Lau, Marc De Graef +1

We examine magnetic domain patterns in symmetric [Co/Ni]${}_M$ and asymmetric [Pt/(Co/Ni)${}_M$/Ir]${}_N$ multi-layers using Fresnel mode Lorentz transmission electron microscopy (LTEM).…
