[17p-B401-2] Modelling of Bulk Superconductor Magnetisation: A Review

Mark D Ainslie1 (1.Dept. of Engineering, Univ. of Cambridge)

Keywords:bulk superconductors, numerical modelling, pulsed field magnetisation

In this presentation, a review of the current state-of-the-art in modelling the magnetisation of bulk superconductors is given, including bulk (RE)BCO (where RE = rare earth or Y), MgB2 and iron-pnictide materials. Such numerical modelling is a powerful and cost-effective tool to understand the physical mechanisms of bulk superconductor magnetisation, to assist in interpretation of experimental results, and to predict the performance of practical bulk superconductor-based devices, which is particularly important as many superconducting applications head towards the commercialisation stage of their development in the coming years. The presentation highlights the differences between simulating the different magnetizing techniques – zero field cooling (ZFC), field cooling (FC) and pulsed field magnetisation (PFM) – as well as the differences and similarities in the assumptions made for the numerical simulation related to different bulk materials.
