Abstract
The resistive transition to the superconducting (SC) state in alpha-(ET)(2) NH4Hg(SCN)(4) was studied under magnetic fields applied parallel to the con ducting plane. The SC state is divided into three regions: (1) temperature- dependent resistive region, (2) zero-resistive region, and (3) temperature- independent resistive region. We observed twofold symmetry in the resistanc e under an in-plane magnetic field near the midpoint of the SC transition, which indicates that the upper critical field mu(0)H(c2) has the same twofo ld symmetry. This in-plane anisotropy can be ascribed to the crystal struct ure.
