摘要：

In order to magnetize the bulk superconductors more strongly by pulsed-field magnetization (PFM), the temperature rise Delta T(t) and the trapped field B-T of the GdBaCuO bulk cooled down to 10 K have been investigated after applying the five successive (No1-No5) pulsed-field ranging from 4.70 T to 6.04 T. Delta T increased linearly with lowering initial bulk temperature T-s and with increasing strength of the applied field B-ex. From the generated heat (Q) estimation, the difference Q value, Delta Q = Q(No1) - Q(No5) which suggests that the Delta Q nearly stands for the flux pinning loss Q(p) shows the similar B-ex dependence to the B-T value.
