Abstract

We have performed a comparative study of the magnetization behavior with applying pulse fields for Y-Ba-Cu-O and Sm-Ba-Cu-O, which exhibit the different field dependence of critical current densities (Jc's). Time variation of the field was monitored with the Hall probe sensor which is attached to the sample surface by varying the maximum field values from 0 to 2 T. In a low field region, the trapped magnetic field of Sm-Ba-Cu-O was slightly smaller than that of Y-Ba-Cu-O, however, it exceeded the value of Y-Ba-Cu-O in a high field region. The results reflect the Jc-B characteristic of Sm-Ba-Cu-O, in which the Jc values show the secondary peak effect and high field Jc values are higher than those of Y-Ba-Cu-O.
