Abstract

The volume pinning force F-p is investigated as a function of the density of weak interacting defects. With increasing defect concentration and increasing field the quadratic dependence of F-p vanishes abruptly and an almost linear relation dominates. In the transition area F p shows large history-effects. The collective weak pinning interaction is the stable mechanism in that area. Whereas the unsteady flux line lattice configuration which results in high critical currents requires a stabilization obtained at increasing fields and/or increasing defect concentration.
