Title: Reconstruction of vortex lattices at low inductions

Abstract

The nonlocal elasticity and the normal modes of an unpinned flux-line lattice (FLL) in a uniaxially anisotropic supeconductor are considered in the low-induction regime {ital b}={ital B}/{ital B}{sub {ital c}2}{much lt}1 at oblique angles {theta} between {bold B} and the {bold {cflx c}} axis. A novel feature of anisotropic superconductors is {ital strongly} {ital dispersive} {ital shear} {ital moduli} when {theta}{gt}0. Thus, the normal modes of the FLL may become soft away from the zone center, signaling a {bold k}{ne}{bold 0} {ital structural} instability of the distorted hexagonal FLL. Vortex structures of a novel type are thus possible in anisotropic superconductors.
