| Research Abstract |
Recently, fluctuating superconductivity (FSC) have attracted attention because it will be one of the most intriguing interpretations of the pseudogap formation, which is likely an intrinsic property in strongly correlated two-dimensional (2D) superconductors. Although a number of experiments has been performed to reveal origin of FSC, it remains unclear so far. In this study, to investigate the origin, we have performed the resistance and magnetic torque measurements for four kinds of superconductors (organics and cuprates), which have different transition temperatures (Tc), electron correlation and dimensionality, respectively. As a result, the FSC was observed in all of the superconductors irrespective of the electron correlation strength and magnitude of Tc. Instead, the temperatures where the FSC appears, tend to enhance in the high 2D sample. Consequently, the origin of FSC can connect to dimensionality rather than the electron correlation and Tc.
