Abstract Magnetization measurements have been performed on single crystals of the organic superconductor {kappa}-(BEDT-TTF){sub 2}Cu(SCN){sub 2} with the field parallel to the {ital a} axis (perpendicular to the conducting plane). At high temperatures, the magnetization {ital M} displays a power-law dependence on {ital H} with {ital M}{proportional_to}{ital H}{sup {alpha}} and {alpha}={minus}0.45{plus_minus}0.05. At low temperatures ({ital T}{le}7.5 K), an anomalous field dependence in {ital M}({ital H}) is observed. The irreversibility field determined from magnetic hysteresis loops displays a universal temperature dependence, i.e., from a high-temperature power-law dependence to a low-temperature exponential dependence. The results are qualitatively similar to the fishtail magnetization reported for the highly anisotropic oxide superconductors. {copyright} {ital 1996 The American Physical Society.}
