Magnetic skyrmions are localized topological spin structures characterized by spins wrapping a unit sphere, and carrying an integer topological charge Q. Their topological properties ensure the inherent stability that makes them technologically appealing for future memory devices.

An international collaboration between Alessandro Stroppa (CNR-SPIN), Fei Wang, Coen de Graaf, Josep M. Poblet (Universitat Rovira i Virgili, Spain), Heng Gao (Institute of Physics, Chinese Academy of Sciences) and Branton J. Campbell (Brigham Young University, USA) focused on 2D hybrid perovskites.
