Magnetic microstructure of nanostructured ferromagnets
Rauf S. Iskhakov, Sergey V. Komogortsev · Bulletin of the Russian Academy of Sciences Physics · 2007
The magnetic microstructure of nanostructured ferromagnets is an ensemble of stochastic magnetic domains—regions with sizes of the same order of magnitude as the length of magnetic orientation coherence. It is shown that the magnetization saturation curves can be used to determine the size of an element of the micromagnetic structure (stochastic domain size) and the effective anisotropy in this element, the size of a nanostructure element and its local anisotropy, and the dimension of exchange-coupled ferromagnetic nanoparticles.
