Abstract: In this work, the structure of magnetic inhomogeneities in ferromagnets localized on 3D defects has been studied. The case of a magnetic defect leading to a spherically symmetric inhomogeneity of the magnetic anisotropy constant is considered. A possible structure of magnetic inhomogeneities of the 0-degree domain wall type localized on the defect is proposed. A type of spherically symmetric defect is found, on which the generation of stable magnetic inhomogeneities of this type is possible. The energy of a 0-degree domain wall is calculated and the conditions for its origin are considered.

Keywords: ferromagnet, defect, domain wall.
