Abstract

We show that thermally activated interstitial and vacancy defects can lead to first-order melting of a vortex lattice. We obtain good agreement with experimentally measured melting curve, latent heat, and magnetization jumps for YBa₂Cu₃O_7\ensuremath-\ensuremathδ and Bi₂Sr₂CaCu₂O₈. The shear modulus of the vortex liquid is frequency dependent and crosses over from zero at low frequencies to a finite value at high frequencies. We also find a small surface tension between the vortex line liquid and the vortex lattice.
