Abstract
The elastic properties of the flux line lattice (FLL) in type II superconductors are calculated from the linearized Ginzburg-Landau (GL) theory for large inductionsB≈H c2 . They appear to be strongly nonlocal, i.e., the elastic modulic 11 andc 44 for homogeneous deformations do not apply if the strain field varies over distances λ/(1−B/H c2 )1/2 ≫d (λ is the penetration depth,d is the FL distance). For smaller strain wavelength,c 11 andc 44 are smaller by factors (1−B/H c2 )2/2κ2 and (1−B/H c2 )/ 2κ2, respectively. The order parameter and local field of a deformed FLL exhibit the expected spatial “frequency modulation,” but also a pronounced “amplitude modulation” whose degree of modulation increases with the strain wavelength. The results of further calculations avoiding the linearization of the GL theory are given.
