Disorder effect on flux lattice melting near Hc2
Abstract
The perturbation series for the three dimensional free energy of Ginzburg-Landau model in a random potential is investigated for a strong magnetic field. The shift of the melting temperature of vortex lattice caused by the white noise random potential is evaluated. The crossover between the “vortex-glass” phase and the “gauge-glass” phase is discussed for a strong disorder.
