Effects of point defects on the phase diagram of vortex states in high-Tc superconductors in B//c axis

Abstract

The phase diagram for the vortex states of high-$T_{\mathrm{c}}$ superconductors with point defects in $\vec{B}\parallel c$ axis is drawn by large-scale Monte Carlo simulations. The vortex slush (VS) phase is found between the vortex glass (VG) and vortex liquid (VL) phases. The first-order transition between this novel normal phase and the VL phase is characterized by a sharp jump of the density of dislocations. The first-order transition between the Bragg glass (BG) and VG or VS phases is also clarified. These two transitions are compared with the melting transition between the BG and VL phases.
