Order and Creep in Flux Lattices and CDWs Pinned by Planar Defects
Abstract
The influence of randomly distributed point impurities and planar defects on the order and transport in type-II superconductors and related systems is considered theoretically. For planar defects of identical orientation the flux line lattice exhibits a new glassy phase dominated by the planar defects with a finite compressibility, a transverse Meissner effect, large sample to sample fuctuations of the susceptibility and an exponential decay of translational long range order. The flux creep resistivity for currents J parallel to the defects is (J) -(J0/J)3/2 . Strong disorder enforces an array of dislocations to relax shear strain.
