The emergent field of curvilinear magnetism introduced new fundamental effects in condensed matter. The physics in these systems is driven by the interplay between exchange and magnetostatic interactions, which contain spatial derivatives in their energy functionals. This makes both interactions sensitive to the appearance of bends and twists in the physical space. At present, the theory is built on the assumption that for small nanostructures, non‐local magnetostatic effects can be neglected and local approximation is valid. Here, Oleksii M. Volkov et al. (article no. 1800309) challenge this assumption by studying experimentally and theoretically the impact of curvature‐induced effects on the equilibrium magnetic states in parabolic nanostripes with different geometrical parameters. The comparison of experimental and theoretical data allows one to identify analytically the geometrical limitations of the presently used theory with local magnetostatics. These results determine the applicability of the existing theoretical framework for further analytical considerations of equilibrium magnetization states of curvilinear nanomagnets.
