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