The samples were characterized structurally by means of X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectrometry. The electrical transport properties of the samples were analyzed in the temperature range between 20-140 K under magnetic fields up to 2 T. The superconducting transition temperature, T-c, and activation energy, U-0, were found to decrease with Lu-doping and with increase in applied magnetic field.eninfo:eu-repo/semantics/closedAccessYBCO superconductorActivation energyRare earth dopingArticle2651945194910.1007/s10948-012-2070-72-s2.0-84959228984Q2WOS:000323906600099Q3
