Here, we propose a new mechanism to stabilize chiral N\\'{e}el skyrmion states relying on the \\textit{gradient} of curvature. We illustrate our approach with an example of a magnetic thin film with perpendicular magnetic anisotropy shaped as a circular indentation. We show that in addition to the topologically trivial ground state, there are two skyrmion states with winding numbers $\\pm 1$ and a skyrmionium state with a winding number $0$. These chiral states are for","authors_text":"Avadh Saxena, Denis D. Sheka, Denys Makarov, Oleksandr V. Pylypovskyi, Volodymyr P.
