Abstract
Magnetization measurements on high-quality single crystals of κ-(BEDT−TTF)2Cu(NCS)2 [where BEDT-TTF denotes bis(ethylenedithio)tetrathiafulvalene] are performed in the magnetic field perpendicular to the conducting layers. An anomalous second peak on magnetization curves observed at Hp (≈ 150 Oe) is attributed to the dimensional crossover in the vortex system. At the dimensional crossover field B2D=φ0(γ2s2), the temperature dependence of the irreversibility field changes from the power-law dependence in the three-dimensional (3D) regime below B2D to the exponential dependence with 1T in the quasi-2D regime above B2D. It is also found that the different magnetic field dependence of the critical current density above and below B2D is well described by the collective pinning theory.
