抜粋

A trapped magnetic field BTP as high as 4.47 T, which is the highest reported using pulse field magnetization to date, has been realized on the surface of a GdBaCuO bulk superconductor by a modified multi pulse technique combined with stepwise cooling. Following an introduction of a small amount magnetic flux into the bulk center by applying lower pulse fields Bex = 4.5-4.6T twice at a higher starting temperature Ts = 45-48 K, higher fields of Bex = 6.6-6.7T are applied three times at a lower Ts =28-29 K. The reduction in the temperature rise due to the already existing trapped flux, in addition to the optimization of the higher Bex value at the lower Ts, is a key point in enhancing BTp
