Abstract:	The peak effect and the quasiorder-disorder phase transition for type-II conventional and high-Tc superconductors have been investigated by taking into account both the quenched disorder and the thermal fluctuations of the vortex lattice. The peak value of the critical current density, the exact peak position and its corresponding half-width for a constant temperature as well as for a constant applied magnetic field have been calculated for type-II superconducting films and bulk materials in the non-dispersive regime of the vortex bundle, and all of the results from the experiment are in agreement.
