Flux line lattice

The collective behavior of condensed modulated structures like charge or spin density waves (CDWs/SDWs) [23, 22, 4], flux line lattices [2, 36] and Wigner crystals [4] in random environments has been the subject of detailed investigations since the early 1970s. These were motivated by the drastic influence... 

The concept of an elastic coherence length was first introduced in the context of charge density waves [28,62] and flux line lattices in superconducters [262], The relevance of this concept for friction was suggested by Baumberger and Carol [54] The contact can be decomposed into pinning centers, also called Larkin domains, with a typical linear size which constitute the BK blocks introduced in the beginning of this section.

Obst has developed a decoration technique for investigating normal and superconducting regions in superconductors. In the intermediate state in lead, the phase boundaries are oriented along cube edges. Other type I superconductors also show correlations between orientation of the flux-line lattice and the crystal lattice.
