摘要：

The peak effect PE is considered to signal the collapse of shear modulus of a weakly pinned flux line lattice. The observed reentrant behavior in PE curves (for H parallel to c, parallel to a) of very clean single crystals of anisotropic superconductor 2H-NbSe2 (T-c = 7.1 K) resembles the predicted reentrant melting curve for pure Abrikosov lattice. The disappearance of PE phenomenon at low fields also appears consistent with the expected crossover to disordered state when intervortex spacing far exceeds the penetration depth.
