摘要
In the organic superconductor kappa-(BEDT-TTF)(2)Cu(NCS)(2), the dynamic relaxation rate (R) of the magnetization curves is investigated using a micro Hall probe in the field perpendicular to the two-dimensional conduction layer. R shows a characteristic dip-like minimum in a narrow field region where the second magnetization peak on the increasing branch appears. This behavior of R indicates the existence of an intermediate state between the ordered and disordered vortex phases.
