✦ Synopsis
In order to magnetize the bulk superconductors more strongly by pulsed-field magnetization (PFM), the temperature rise DT(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. DT 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, DQ = Q(No1) À Q(No5) which suggests that the DQ nearly stands for the flux pinning loss Q p shows the similar B ex dependence to the B T value.
