摘要：
The pinning properties of vortices of four different compounds of the kappa-(BEDT-TTF)(2)X family are presented. From the characteristic energies for pinning, we establish scaling laws for the evolution of the penetration depth and the anisotropy with respect to chemical pressure. These quantities are then deduced as unpinning in the liquid phase is attributed to disentanglement of the flux lines.
