摘要：
The superconductivity (SC) of a layered organic salt beta-(BDA-TTP)(2)SbF6 with a new donor molecule centered with tetrathiapentalene (TTP) has been characterized by the temperature dependence of the upper critical field H-c2(T) and the specific heat. The SC transition behaviors observed via the resistive and magnetic susceptibility measurements are different at finite temperatures, probably due to the influence of vortex dynamics. The SC parameters including the coherence lengths are evaluated based on the H-c2(0)'s in tire magnetic fields applied parallel and perpendicular to the SC plane, in combination with the specific heat data.
