Закрепление потока в сильных магнитных полях в проводниках с покрытием REBa2Cu3O7-x
Ключевые слова:
REBa2Cu3O7-x, закрепление потока, сильные магнитные поля
Аннотация
REBa2Cu3O7-x (REBCO) – основа высокотемпературных сверхпроводящих лент второго поколения – отличается прекрасными характеристиками, такими как высокое необратимое поле (7 Т) и высокая пропускная способность по току (77 К, 106 А/см2). REBCO рассматривается как потенциальный выбор для применения в условиях сильных магнитных полей (ускорители, магнитно-резонансная томография (МРТ)). В последние годы была разработана тонкопленочная технология эпитаксии и двухосных текстур на основе гибких подложек, которая может помочь преодолеть слабое соединение границ зерен и плохие механические свойства REBCO. Однако серьезной проблемой остается ухудшение критической плотности тока Jc в этих пленках из-за вихревого движения в их магнитном поле. Установлено, что закрепление потока в проводниках с покрытием REBCO может улучшить критическую плотность тока при высоких магнитных полях, что означает благоприятные условия для применения REBCO в будущем. В статье кратко описывается механизм, вводные методы и изменчивость закрепления магнитного потока в зависимости от условий окружающей среды. Описан процесс закрепления проводников с покрытием REBCO потоком при высоких магнитных полях. Проведен анализ идеальной структуры закрепления магнитного потока проводников с покрытием REBCO в сильном магнитном поле.
