Перемагничивание наночастицы циркулярно-поляризованным магнитным полем

Abstract

Изучено влияние внешнего поля, поляризованного в плоскости, перпендикулярной оси легкого намагничивания сферической одноосной ферромагнитной наночастицы, на динамику ее магнитного момента. Теоретически и численно показана возможность переключения намагниченности наночастицы циркулярно-поляризованным полем. Установлены количественные критерии перехода магнитного момента из режима однородной к режиму неоднородной прецессии и продемонстрирована их зависимость от предыстории состояний. // Eng The influence of an external magnetic field polarized in the plan perpendicular to the easy axe of a spherical uniaxial ferromagnetic nanoparticle on the dynamics of its magnetic moment is studied. The possibility of the nanoparticle’s magnetization switching is shown theoretically as well as numerically. Quantitative criteria for transition of the magnetic moment from uniform to non-uniform precession are revealed and their dependence on the state’s history is demonstrated.
