Superconductivity of individual grains and inter-grain boundaries for polycrystalline FeSr2YCu2O6+y

Polycrystalline FeSr2YCu2O6+y was synthesized and its transport and magnetic properties were studied. Diamagnetism was observed below 60K. Zero resistivity was observed below 38K under zero magnetic field and below 10K under 160kOe. A two-step transition was observed in resistivity measurement due t...
