Essay

In dissertation research the processes of self-organization of initial array of freely mobile magnetic nanoparticles (in a liquid) in planar and linear clusters are represented. The influence of the external field and perpendicular anisotropy of easy axis type on the structure of ground (vortex) state are investigated. Research of dynamic descriptions of one-dimensional (1D) chainlike clusters is conducted, namely: the spectrums of resilient and magnetic vibrations, the stability criterion of the chainlike cluster is formulated. It is discovered that the structure (distributing of matter) of nanoparticles strongly influences on the effects of hybridization of magnetic and resilient branches of the spectrum. Exact equations for the spectrum of resilient vibrations of chain and equations which describe a soliton distribution in the system are got.
