Abstract

The effect of CdTe addition on YBa2Cu3O7−δ(CdTe)x (x = 0–0.10) has been studied. XRD patterns showed the presence of impurities including CdTe for x ≥ 0.05 wt%. The resistance versus temperature curves showed metallic behavior for all samples. The onset temperature Tc onset for all samples is between 90 and 92 K. The superconducting transition width, ΔTc = 4 K for all samples except for x = 0.1 wt% where ΔTc = 6 K. The superconducting transition determined by AC susceptibility measurement also showed little change in (Formula presented.) (between 89 and 92 K). However, the peak temperature Tp of the imaginary part of the susceptibility χ″, showed a drastic decrease for samples with x > 0.05 wt%. This indicated that the superconducting grains were strongly decoupled for x > 0.05 wt% due to the impurities as observed in the XRD pattern. The intergrain critical current density, Jc at Tp for the x = 0 sample is Jc (82 K) = 17 A cm−2. These results can be useful in the fabrication of semiconductor/YBCO superconductor hybrid systems.
