Özet
This study manifests the change of pinning mechanism, electrical, structural, physical, mechanical and superconducting properties of YBaCuGdO superconductors samples prepared by the conventional solid-state reaction method (x= 0, 0.025, 0.050, 0.100 and 0.150) by use of dc resistivity, X-ray analysis (XRD), scanning electron microscopy (SEM) and Vickers microhardness measurements. Zero resistivity transition temperatures (T) of the samples are deduced from the dc resistivity measurements. Additionally, the lattice parameters are determined from XRD measurements when the microstructure, surface morphology and microhardness of the samples studied are examined by SEM and mechanical measurements, respectively. The results obtained demonstrate that T values of the samples decrease slowly with the increase in the Gd content. The maximum T (92.0 K) is obtained for the pure sample prepared at …
