The GdBaCuO superconducting bulk with stronger pinning characteristics (B T = 1.8 T at 77 K by the field cooled magnetization (FCM)) has been magnetized at T s = 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 T s, the pinning force F p 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 T s, the SPA technique is not necessarily a suitable technique to enhance the trapped field B T and the total trapped flux Phi T. However, these values can be enhanced by the MMPSC method. The properties of the bulk with stronger pinning characteristics during PFM are discussed.
