Abstract
Preparation, X-ray diffraction (XRD), resistivity (ρ) and magnetic susceptibility (χ) of YSrCuO y (nominal composition) synthesized at 1200°C are reported. XRD data indicate more than one phase. Zero resistivity is observed at 72 K. The field cooled χ indicates a superconducting transition at 68 K and also an anti-ferromagnetic transition at 15 K which could be due to Y 2 Cu 2 O 5. These data confirm the earlier observations of Wu et al.5 who have, however, observed a higher T c at 85 K which could be due to a higher temperature used for synthesis.Keywords
