Abstract

A new class of low-amplitude magnetic defects in an infinite medium and the film three-dimensional ferromagnetic materials in the Heisenberg model are found. Such structures contain sources and vortices. It is shown that their dipole configurations have finite energy. A stability of structures are discussed.

PACS: 75.60.Ch Domain walls and domain structure;
PACS: 75.25.+z Spin arrangements in magnetically ordered materials.

Key words: Heisenberg model, domain vortices, non-linear sources, Landau–Lifshitz equation, dipole.
