Abstract
Resistance measurements have been performed to investigate the superconducting state for an organic superconductor (TMET−STF)2BF4 with Tc=4.1K. The upper critical magnetic fields parallel and perpendicular to the conduction plane are determined and dimensional crossover from three dimensions (3D) to 2D in the superconducting state is found at 3.5 K. The anisotropy of the critical field has a maximum at the crossover. The temperature dependence of the superconducting transition width is qualitatively understood in terms of the thermal activated flux motion and the crossover.
