Essay

The thesis deals with the dynamics of the magnetic moment of the uniaxial ferromagnetic nanoparticle driven by a rotating magnetic field. The condition of generation of uniform and non-uniform precession modes are established as well as the condition of remagnetization of nanoparticle using such a field. The analysis of the lifetime of precession modes of nanoparticle magnetic moment under action of rotating field and thermal bath is completed. The optimal field characteristics for the magnetic moment switching were found. The influence of thermal fluctuation on the magnetic moment switching is investigated.
