Strong stray fields in systems of giant magnetic anisotropy magnets

This paper reviews research into a little-studied phenomenon in which strong stray fields arise in ferromagnets with giant magnetic anisotropy. Conditions for this to occur and for the fields to be stable are discussed. A classification of strong fields is presented. For different field types, limit...

Zusammenfassung:This paper reviews research into a little-studied phenomenon in which strong stray fields arise in ferromagnets with giant magnetic anisotropy. Conditions for this to occur and for the fields to be stable are discussed. A classification of strong fields is presented. For different field types, limiting field strength values on approaching singular points are determined. Applications of the stray fields in various technical devices are considered.
