Monte Carlo simulations of vortex dynamics in high-temperature superconductors under pulsed-field magnetization

International audienceThe influence of pulsed-field magnetization on a high-temperature superconductor has been numerically studied using the Monte Carlo method. Calculations have been done for a broad range of pulse parameters, such as amplitude and shape, and the sample parameters, such as temperature and the concentration and type of distribution of defects. The dependences of penetrated magnetic field on the calculation time have been obtained and jump-like features have been observed. Trapped field profiles have been calculated for various conditions and the optimal pulse and sample parameters have been determined
