Carbon (C) and rare earth oxide (REO) co-doped bulk polycrystalline MgB₂ samples with nominal compositions Mg1 − y(REO)y(B0.95C0.05)₂ (where y = 0.00, 0.01, 0.03, 0.05 and REO = Eu₂O₃ or Pr₆O₁₁) have been synthesized via a solid state reaction route. The XRD results reveal the presence of impurity phases EuB₆ in...

In this paper we report the effect of carbon doping on the structural and superconducting properties of MgB₂ using citric and oxalic acids as carbon sources. The bulk polycrystalline samples have been synthesized via a standard solid state reaction route with composition MgB₂+x wt% of citric and oxalic acids (x = 0, 5 and 10). The x-ray diffraction results reveal the formation...
