Abstract :
Nucleation fields of nanostructured two-phase magnets with soft magnetical grains embedded in a hard magnetic matrix are examined using Brown´s equation. We showed that the nucleation fields depend not only on the relative magnetic properties of soft and hard magnetic phases, but also on the sizes of both phases and the arrangement of soft magnetic grains within the hard magnetic matrix
