Numerical evaluation of magnetization properties of a bulk HTSC with a hole

摘要

Field-cooled and pulsed field magnetizations of a bulk high T/sub c/ superconductor (HTSC) with a hole are evaluated by using thin plate multi layers numerical codes. Dynamic effects of the pulsed field magnetization is analyzed with the flux creep-flow model. Merits and demerits of the HTSC with and without a hole are discussed from their practical applications as a trapped field magnet.
