Abstract
The flux‐line lattice in a type‐II superconductor in the remanent state is investigated by means of a decoration method. The triangular lattice contains various kinds of defects, the most important of which are flux‐line dislocations. A critical lattice parameter dc exists such that for lattice parameters d>dc the flux lines form no longer a lattice but a ``flux‐line fluid.'' A belt directly underneath the specimen surface is free from flux lines. The transition from the ``fluid'' to the flux‐free region has been utilized to estimate in a fairly direct way the pinning forces acting on the flux lines.This publication has 12 references indexed in Scilit:
