Notes:
2 ZrO5.5 has been synthesized by solid-state reaction. Structural ordering in this material has been studied by X-ray diffraction (XRD). The XRD spectra reveal that DyBa2ZrO5.5 has an ordered complex cubic perovskite structure. The presence of superstructure reflections in the XRD spectra is characteristic of A2BB’O6-type crystalline structure. The chemical stability of DyBa2ZrO5.5 with YBa2CuO7-δ (YBCO) superconductors has been studied by XRD and electrical resistivity measurements. These studies show that DyBa2ZrO5.5 is chemically stable with YBCO and there is no degradation in the superconducting transition temperature Tc of YBCO even when mixed up to 1:1 vol%, with DyBa2ZrO5.5 in YBCO. Detailed study of the superconducting transition region shows that Tc(onset) and Tc(0) values of pure YBCO and YBCO–DyBa2ZrO5.5 composites are similar in both cases. The implications are discussed.
