Title :垂直磁界中の超伝導平板におけるベクトルポテンシャル分布
Authors :野田 稔

Abstract :A shielded region in a superconducting plate under a perpendicular magnetic field is surrounded by two regions of current flowing in opposite directions each other. This front configuration can be well approximated by a curve similar to a parabola, but having a power of the nth order. In this study, vector potentials produced by these currents are calculated in the space including the superconducting plate. The equipotential value gives a visual determination of the flux line distribution, from which we can estimate a shielding effect near or inside the current front. For example, adopting appropriate pa — rameters of the nth power curve, we can find a flux line flowing very closely to the front curve. The potential value corresponding with the flux line is about 0.1 % of the external filed potential. Distribution of the potential inside the shielded regions is then examined precisely. As a result, it is found that any shielded potential inside the front curve can be suppressed to below 0.1 % of the external filed potential.
