Магнитная релаксация в двухмерных ансамблях наночастиц: приближение среднего поля

Abstract

В рамках приближения среднего поля изучен закон магнитной релаксации для двухмерных ансамблей сферических наночастиц, распределенных по узлам квадратной решетки. Показано, что магнитная релаксация в таких ансамблях характеризуется начальным и конечным временами релаксации и что их отличие обусловливает замедление релаксации. Выведена приближенная формула, описывающая временнýю эволюцию намагниченности. // Eng The law of magnetic relaxation for two-dimensional ensembles of uniaxial spherical nanoparticles distributed on the sites of a square lattice is studied within the mean-field approximation. It is showed that magnetic relaxation in those ensembles is characterized by the initial and final relaxation times and that their difference determines the deceleration of relaxation. The approximate formula describing the time-evolution of magnetization is derived. При цитировании документа, используйте ссылку http://essuir.sumdu.edu.ua/handle/123456789/2630
