摘要：

We studied the dynamical motion of flux lines in melt-processed Sm-Ba-Cu-O (SmBCO) bulk-superconductors driven by a magnetic pulse at 77 K. The total amount of trapped magnetic flux (Phi(T)) as a function of the magnitude of pulse exhibited a peak; the decrease of Phi(T) for large pulses is attributed to the increase in temperature of the sample due to the resistive force exerted on moving flux lines. Compared to melt-processed Y-Ba-Cu-O, it is found that the penetration of Bur lines into the sample requires a larger pulse, reflecting the strong pinning effect of SmBCO.
