The solution method is based on simplifying the equation using the first integrals, which are determined using the analogy between the inertial motion of magnetization and the mechanical rotation of a solid. It is shown that accounting for the magnetization inertia causes the nutation at a frequency represented by means of a complete elliptic integral of the first kind. The dependence of the nutation amplitude on the external field value is discussed.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324527456">Получены аналитические решения инерционного уравнения Ландау–Лифшица–Гилберта для продольной и поперечной компонент намагниченности однодоменной ферромагнитной наночастицы в условиях, близких к насыщению. Метод решения основан на упрощении уравнения с помощью первых интегралов, которые находятся с использованием аналогии между инерционным движением намагниченности и механическим вращением твердого тела. Показано, что учет инерции намагниченности приводит к нутации, частота которой представлена через полный эллиптический интеграл первого рода. Рассмотрена зависимость амплитуды нутаций от величины внешнего поля.</p></trans-abstract><kwd-group xml:lang="en"><kwd>single-domain ferromagnetic nanoparticle</kwd><kwd>Landau‒Lifshitz‒Gilbert equation</kwd><kwd>magnetization</kwd><kwd>mechanical rotation</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Neeraj K., Awari N., Kovalev S. et al. // Nature Phys. 2021.
