摘要：

Influence of the external magnetic field polarized in a plane, which is perpendicular to the axis of easy magnetization of a spherical uniaxial ferromagnetic nanoparticle on dynamics of its magnetic moment is studied. The opportunity of switching of magnetization of a nanoparticle by the polarized field is shown theoretically and numerically. The quantitative criteria for transition of a magnetic moment from a uniform precession mode to a nonuniform one are revealed, and their dependence on previous history of states is demonstrated.
