Abstract The de Haas–van Alphen (dHvA) oscillation was observed in the superconductivity mixed state near the upper critical field H c2 of the two-dimensional organic superconductor κ-(BEDT-TTF)2Cu(NCS)2. By analyzing an additional damping of the oscillation, the superconductivity fluctuation effects near H c2 are elucidated quantitatively as the magnetic field dependence of the mean square of the superconducting gap. By rotating the external magnetic field, the angular dependence of the fluctuation effects and probable values of the H c2 are studied.
