Dimensional cross-over in collective flux pinning
Physica B+C, 1985Abstract We report a new effect regarding the collective flux pinning in sputtered amorphous Nb3Ge films. Thick films (d = 5−8 μm) show the two dimensional collective pinning (2DCP) at low fields and all temperatures. Below 0.7Tc, however, an extremely sharp and large peak develops in the macroscopic pinning force at fields around 0.75Bc2.

Philosophical Magazine, 1977
Abstract Measurements of pinning forces in two model system superconductors containing either incoherent normal-conducting or coherent superconducting precipitates are reported. An analysis of the bulk pinning forces shows that in both cases the statistical summation of basic interaction forces is appropriate.

Flux-line pinning by competing disorders
Physical Review B, 1993Localization of flux lines by columnar defects is investigated in the presence of point disorder. A (1+1)-dimensional model is analyzed in some detail. When point disorder is weak, the phase transition is found to be of the Bose-glass type. Some aspects of the Bose-glass phase itself may be marginally unstable to weak point disorder, but only beyond an

The main advantage of superconductors, that these materials can transport electric current without energy dissipation, is achieved by the mechanism of flux pinning. Quantized flux lines that contain superconducting structure inside do not move under interaction with defects in the superconductor, even when the Lorentz force is present due to the ...

Flux Pinning in A15 Superconductors
Japanese Journal of Applied Physics, 1987Global pinning force is influenced greatly by microstructures like grain size and third elements, when Nb3 Sn and V3 Ga superconductors are prepared by various different techniques. The structure dependence of flux pinning has been investigated in details. The main flux pinning center was attributed to the grain boundary.
