Effect of MgB2 additives on structure, electrical and thermal properties of Eu1Ba2Cu3O7

The effect of MgB2 addition on the Eu1Ba2Cu3O7 (EBCO) ceramics was systematically studied. Series of Eu1Ba2Cu3O7 + x(MgB2) samples (x = 0 wt.%, 0.05 wt.%, 0.1 wt.%, 1 wt.%, 3 wt.%) were prepared using traditional solid state method. X-ray powder diffraction measurements were used for phase identification. The lattice parameters and or-thorombicity decreased with MgB2 addition. A standard four point measurement method was used to determine transition temperatures T-c of superconducting samples. T-c values of the samples were decreasing with MgB2 concentration. TGA results indicate thermal stability of doped samples.
