Abstract
The GdBaCuO superconducting bulk with stronger pinning characteristics (BT = 1.8 T at 77 K by the field cooled magnetization (FCM)) has been magnetized at Ts = 70 - 20 K by the pulsed field magnetization (PFM) techniques; a sequential pulsed-field application (SPA) and a modified multi pulse technique with stepwise cooling (MMPSC). With decreasing Ts, the pinning force Fp increases especially at the growth sector boundaries (GSBs), and then the nonuniformity of the trapped field profile becomes more and more conspicuous on the bulk surface. At low Ts, the SPA technique is not necessarily a suitable technique to enhance the trapped field B T and the total trapped flux φT However, these values can be enhanced by the MMPSC method. The properties of the bulk with stronger pinning characteristics during PFM are discussed.
