Abstract

We report measurements on the anisotropic critical field, the angular dependent magnetoresistance, and Shubnikov de Haas oscillations in α-(BEDT-TTF)₂NH₄Hg(SCN)₄, the only ambient pressure superconductor (T_c = 1.2K) in the α-(BEDT-TTF)₂MHg(SCN)₄ organic conductor family. The anisotropic critical field is well described by a 2-D model for layered superconductors where the anisotropy ε = H_c///H_c⊥ is approx. 25 at low temperatures, and rises to approx. 100 near T_c. Beating behavior is observed in the SdH effect in tilted magnetic fields.
