Abstract

In this paper, we report the doping effects of succinic acid, C₄H₆O₄ (from 0 to 30 wt%) on the lattice parameter, critical temperature (T_c), critical current density (J_c), upper critical field (H_c2), and irreversibility field (H_irr) in MgB₂ superconductor. It was found that MgB₂ doped with 10 wt% C₄H₆O₄ and sintered at 900°C exhibited excellent J_c above 10⁴ Acm⁻² at 5 K and 8 T. Impurity scattering due to C substitution, improved crystallinity and the least amount of MgO in 10 wt% doped sample improves Jc very significantly. The MgO amount is rapidly increased in 20 and 30 wt% doped samples which causes a strong depression of J_c, H_c2, H_irr due to poor inter and intra-grain connectivity.
