Abstract

In order to magnetize the bulk superconductors more strongly by pulsed-field magnetization (PFM), the temperature rise ΔT(t) and the trapped field BT 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. ΔT increased linearly with lowering initial bulk temperature Ts and with increasing strength of the applied field Bex. From the generated heat (Q) estimation, the difference Q value, ΔQ = Q(No1) - Q(No5) which suggests that the ΔQ nearly stands for the flux pinning loss Qp shows the similar Bex dependence to the BT value.
