Abstract

In this paper, we investigated the influences of Na substitution on the enhancements of critical current density (J_c) in the BiPbSrCaCuO (BPSCCO) superconductors. The Bi_1.6Pb_0.4Sr₂Ca₂ ¹ _xNa_xCu₃O₁₀+_¤ (where x was ranged from 0 to 0.1) polycrystalline samples were fabricated using solid state reaction technique. The zero electrical critical temperature (T_c) of Na-substituted BPSCCO samples was found to be slightly higher than that of Na-free BPSCCO one. Magnetization J_c data measured at 65 K with field applied parallel to the c-axis of the samples showed that J_c of Na-substituted BPSCCO samples were enhanced. Possible reasons for the J_c enhancements were attributed to the effective flux pinning by crystal defects at Ca layers generated by Na substitution. Improvements of volume pinning force (F_p) in terms of magnitude and position of F_pmax were also obtained.
