У двовимiрному феромагнетику теоретично дослiджено динамiку вихор-антивихрової пари в присутностi нерухомого вихору. Розрахунки проведено в рамках моделi колективних змiнних. Отримано критерiї для початкових умов, що дозволяють роздiлити фiнiтний та iнфiнiтний рух пари. Дослiджено загальнi характеристики кожного з типiв рухiв.
В двумерном магнетике теоретически исследована динамика вихрь-антивихревойal ferromagnet is theoretically studied. The calculations are performed within the model of collective variables. Criteria for the initial conditions allowing one to separate the finite and infinite motions of the pair are obtained. General characteristics of each of the types of motion are described.
