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 YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} and Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}. 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. (c) 2000 The American Physical Society.
