抄録

For theoretical clarification of mechanism of a pulsed-field magnetization (PFM) and development of more efficient PFM method, we carried out a detailed computer simulation in consideration of the difference in the superconducting characteristics between the growth sector boundary (GSB) and the growth sector region (GSR) parts of the material. The superconducting current was defined in each part and the magnetic field induced by the local current was calculated. The entire magnetic field distribution was obtained by adding individual distributions. The experiment with a Sm123 bulk superconductor was performed and it was confirmed that the calculated distribution reproduces the experimental one.
