Superconductivity at 7.5 K and ambient pressure in polycrystalline pressed samples of βp-(BEDT-TTF)2I3


  • We gratefully acknowledge financial support of this work by the Deutsche Forschungsgemeinschaft


Polycrystalline pressed samples of β-(BEDT-TTF)2I3 exhibit bulk superconductivity, zero resistivity being observed at 3.2 K (see figure) a transition temperature which is surprisingly higher than that observed for single crystals of the same compound.
