Abstract

We present a nearly perfect Pauli-limited critical field phase diagram for the anisotropic organic superconductor $\alpha $-(ET)$ _2 $NH$ _4 $(SCN)$ _4 $when the applied magnetic field is oriented parallel to the conducting layers. The critical fields ($ {H_{c_2} $) were found by use of penetration depth measurements. Because$ {H_{c_2}$ is Pauli-limited, the size of the superconducting energy gap can be calculated. The role of spin-orbit scattering and many-body effects play a role in explaining our measurements.
