Магнитодинамика наночастиц в сильном переменном поле
Диссертация
До недавнего времени, пока для записи использовались частицы микронного размера, вполне удовлетворительную теорию процесса давала энергетическая модель Стонера-Вольфарта. Стремление уменьшить физический размер «магнитного бита» естественным образом привело к идее заменить микрозерна наночастицами. Однако в нанодисперсных ферромагнетиках высота энергетического барьера перемагничивания может… Читать ещё >
