Abstract
We study the interplay between a novel vortex-loop unbinding in finite magnetic field at T=TV and flux-line-lattice (FLL) melting at T=TM in type-II superconductors. The FLL melts due to nucleation of vortex loops parallel to the c^ axis, connected to flux lines. For moderate anisotropy, phase coherence parallel to c^ is lost at TV>TM due to an ab-plane vortex-loop unbinding with loops located close to thermal FLL fluctuations. For large anisotropy, phase coherence parallel to c^ is lost at TV<TM due to nucleation of vortex loops uncorrelated to flux lines, predominantly in the ab plane.
