Experimental realization of metastable target skyrmion states in continuous films Open
Target skyrmions (TSks) are topological spin textures where the out-of-plane component of the magnetization twists an integer number of k-π rotations. Based on a magnetic multilayer stack in the form of n × [CoFeB/MgO/Ta], engineered to ho…
