Исследования последних лет привели к обнаружению качеств спинтронных осцилляторов, обеспечивающих их широкое применение на практике как устройств, обрабатывающих и генерирующих сигналы. Существенным ограничением практической реализации спинтронных осцилляторов является их малая  мощность, из-за чего появляется необходимость их синхронизации.  </p></sec><sec><title>Цель работы</title><p>Цель работы. Определение условий реализации синхронного режима двух связанных посредством общего  тока антиферромагнитных спинтронных осцилляторов.  </p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для упрощения численного моделирования системы связанных резистивно антиферромагнитных осцилляторов был использован метод многих масштабов, позволивший рассматривать систему уравнений Курамото вместо исходной. Для определения полосы захвата модели Курамото был применен метод аппроксимации гомоклинической траектории.  </p></sec><sec><title>Результаты</title><p>Результаты. Получено уравнение Курамото для фаз парциальных осцилляторов, учитывающее влияние инерционного слагаемого и фазового сдвига между ними. Получены выражения для полосы захвата и синхронизации как функции параметров системы (токов подкачки, размеров) и проведено численное моделирование, позволяющее количественно определить границы существования двух режимов: синхронного и асинхронного.  </p></sec><sec><title>Заключение</title><p>Заключение. Результаты численного моделирования системы уравнений Курамото и уравнения Адлера для  двух связанных спинтронных осцилляторов соответствуют найденным теоретически значениям полос захвата и синхронизации. Схему приведения модели антиферромагнитных осцилляторов к модели Курамото в дальнейшем можно распространить и на случай большего количества связанных осцилляторов, что позволит  упростить вычислительный эксперимент и существенно сократить время численного моделирования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Recent studies into the properties of spintronic oscillators have led to broadening their scope of practical application as devices for generating and processing signals. The practical implementation of spintronic oscillators is, however, significantly limited by their low power capacity, thus requiring synchronization between devices.</p></sec><sec><title>Aim</title><p>Aim. Determination of conditions for the implementation of the synchronous regime of two antiferromagnetic spintronic oscillators coupled by a common current.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. To simplify the numerical simulation of a system of coupled resistively antiferromagnetic oscillators, the method of multiple-time-scale analysis was used. This allowed a system of Kuramoto equations to be considered instead of the original system. To determine the locking band of the Kuramoto model, the homoclinic trajectory approximation method was applied.</p></sec><sec><title>Results</title><p>Results. A system of Kuramoto equation for the phases of partial oscillators under the influence of the inertial term and phase shift was obtained. Expressions describing the locking and synchronization band as functions of the system parameters (bias currents and sizes) were derived. The numerically simulated Kuramoto model was used to determine the bands of the synchronous and asynchronous regimes.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results of numerical simulations of the system of Kuramoto equations and the Adler equation for two coupled spintronic oscillators agree well with the theoretically calculated values of locking and synchronization ranges. The scheme for reducing the model of antiferromagnetic oscillators to a Kuramoto model can be further extended to the case of a larger number of coupled oscillators, which will simplify computational experiments and significantly reduce the time required for numerical simulations.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синхронизация</kwd><kwd>полоса захвата</kwd><kwd>модель Курамото</kwd><kwd>уравнение Адлера</kwd><kwd>АФМ-осциллятор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>synchronization</kwd><kwd>locking band</kwd><kwd>Kuramoto model</kwd><kwd>Adler equation</kwd><kwd>AFM oscillator</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и  высшего образования Российской Федерации (тема № FFWZ-2022-0015).</funding-statement><funding-statement xml:lang="en">This work was supported by the Ministry of Science and Higher Education of the Russian Federation (project no.
