Abstract
Inductive studies based on rf penetration depth measurements and resistive studies based on 4-lead electrical resistivity measurements are reported for the sulfur-based ambient pressure superconductor β-(BEDT-TTF)2I3. The inductive studies show that the bulk superconducting transition temperature (Tc) is sample dependent, with values of Tc ranging from 1.2 K to 1.4 K. The critical magnetic fields Hc2 show considerable anisotropy in directions perpendicular and parallel to the crystallographic ab plane. The electrical resistivity as a function of temperature shows linear and quadratic dependences on T and unusual structure near 8 K and 4 K.Keywords
