Использование спинтронной компонентной базы значительно повышает быстродействие, уменьшает размеры и снижает энергопотребление современных электронных устройств. Неотъемлемой частью спинтронных устройств является спинтронный осциллятор (СО). Связывание многих СО (&gt; 100) в ансамбли с дальнейшей синхронизацией позволяет нивелировать такие недостатки СО, как малая выходная мощность и высокие фазовые шумы, так как выходная мощность ансамбля СО увеличивается в сравнении с единичным осциллятором, в то время как ширина спектральной линии ансамбля уменьшается.</p></sec><sec><title>Цель работы</title><p>Цель работы.

На основании полученных результатов сделан вывод о преимуществах локальной связи ансамбля СО общим током, обеспечивающей топологию ансамбля "все со всеми", благодаря чему время перехода ансамбля СО в синхронный режим наименее зависимо от отказов в работе осцилляторов и увеличения количества синхронизируемых СО.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The use of spintronic components significantly enhances the performance, reduces the size, and lowers the power consumption of modern electronic devices. The spintronic oscillator (SO) is an integral part of spintronic devices. Connecting several SOs (&gt; 100) into ensembles with subsequent synchronization mitigates such SO drawbacks as low output power and high phase noise. These drawbacks appear as a result of an increase in the output power of an SO ensemble compared to a single oscillator under a simultaneous decrease in the spectral linewidth of the ensemble.</p></sec><sec><title>Aim</title><p>Aim. To investigate the impact of connection topologies, synchronization mechanisms, and oscillator failures on the synchronization of oscillator ensembles.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The Kuramoto phase model was used to simplify the numerical modeling of synchronization of SOs connected into an ensemble.</p></sec><sec><title>Results</title><p>Results. A Kuramoto equation for phases of SOs connected in an ensemble was derived, and the influence of connection topologies and oscillator failures on the synchronization parameters of an ensemble of N connected oscillators was demonstrated.</p></sec><sec><title>Conclusion</title><p>Conclusion. In order to ensure the shortest transition time of an SO ensemble to the synchronous mode, topologies with a higher number of connections between oscillators (e.g., "all-to-all") are preferable. The results obtained confirm the advantages of local connection of an SO ensemble by a common current, thus forming an "all-to-all" topology. This makes the transition time of the SO ensemble to the synchronous mode less dependent on both oscillator failures and the number of synchronized SOs.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>спинтронный осциллятор</kwd><kwd>ансамбли спинтронных осцилляторов</kwd><kwd>синхронизация</kwd><kwd>модель Курамото</kwd><kwd>топология связи</kwd><kwd>отказ осциллятора</kwd><kwd>механизмы связи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>spintronic oscillator</kwd><kwd>spintronic oscillator ensembles</kwd><kwd>synchronization</kwd><kwd>Kuramoto model</kwd><kwd>connection topology</kwd><kwd>oscillator failure</kwd><kwd>synchronization mechanisms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке государственного задания РФ в ИРЭ им.
