Abstract

In this study, the magnetic behavior of the YBCO superconducting (YBa₂Cu₃O_{7- ẟ}) samples prepared with the Sol-gel method, and dopped with 0.2, 0.5, 0.9 and 1.3wt% carbon nanotubes (CNT), were investigated. Using magnetic acceptance analysis, we found that the transition temperature of the samples is not much different from the pure sample. Also, according to the scanning electron microscopic images (SEM), the size of the seeds to the optimum pollution is increased by 0.5, thereby improving inter -grain communication.

Keywords: YBCO superconducting (YBa₂Cu₃O_{7- ẟ}), carbon nanotubes (CNT), sol- gel, transition temperature.
