Skyrmioniums are magnetic textures that can emerge in thin-film magnets under suitable conditions, potentially coexisting with other configurations such as domain walls and skyrmions. They can be understood as two nested skyrmions with opposite topological charge, giving rise to a ring-like, non-topological structure rather than the single-core profile characteristic of skyrmions. In this work, we investigate the stability and internal structure of skyrmioniums in thin films, examining the influence of crystalline anisotropy, external magnetic fields, and the demagnetization field. We present a comparative analysis with skyrmions, highlighting key similarities and differences in their stability regimes and structural responses to material and field parameters.
