Ensembles single-domain ferromagnetic particles. Develop local-mean theory dipolar ferromagnetism and magnetic relaxation in ensembles nanoparticles. Methods based on stochastic Landau-Lifshitz equation and Fokker-Planck equation; Kramers method. In an approximation local-mean dipolar field the theory of dipolar ferromagnetism in system ferromagnetic nanoparticles distributed in solid matrix is developed. For the two-dimensional ensembles of nanoparticles low magnetic relaxation inclusive fluctuations of the dipolar field is developed. Sphere of use is the radio engineering and computer engineering.
