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 (J_c'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 J_c-B characteristic of Sm-Ba-Cu-O, in which the J_c values show the secondary peak effect and high field J_c values are higher than those of Y-Ba-Cu-O.
