Методом Монте-Карло в рамках двумерной модели слоистого ВТСП получено распределение магнитного поля в плоскости образца, формирующееся при протекании транспортного тока. Рассчитаны скорости вихрей в каждой точке образца. Получена зависимость максимальной скорости вихрей от количества центров пиннинга в образце. Результаты будут использованы в дальнейших расчетах отклика сверхпроводника на импульсное воздействие тока, превышающего критический.

Using the Monte Carlo method, the distribution of the magnetic field in the superconductor plane, which is formed during the flow of a transport current, is obtained within the framework of a two-dimensional layered HTS model. The vortex velocities at each point of the sample are calculated. The dependence of the maximum vortex velocity on the number of pinning centers in the sample is obtained. The results will be used in further calculations of the response of a superconductor to a pulsed current exceeding the critical current.
