Abstract

Low temperature upper critical field studies have been carried out in a new organic superconductor β″-(BEDT-TTF)2SF5CH2CF 2SO3. For field parallel to the superconducting layers, the upper critical field determined from transport measurements exceeds the BCS Pauli limit at low temperatures. The angular dependence of the resistive transition shows that the upper critical field can be best described by a quasi-two-dimensional model with a cusp near the field parallel to the plane direction.
