Flux line lattice in deformed superconductor Nb-Mo: Collective pinning and dielastic interaction with screw dislocations

Research output: Contribution to journal › Article › peer-review

Abstract

A detailed investigation of the flux line lattice (FLL) interaction with nonuniformly distributed, mainly screw dislocations in deformed Nb-Mo single crystals has been made using the high resolution technique of decorating a sample by small Fe particles. The interaction has been considered from the point of view both of elementary pinning force summation and of the particular pinning mechanism. The FLL has been observed to split into short-range order regions at a low dislocation density and to be amorphous at densities exceeding 1010 cm-2. The dimensions of these regions determine the critical current value in agreement with the collective pinning theory. The observed distribution of the flux lines has been shown to result from the dielastic ΔE-interaction of the dislocations with the FLL. © 1989 Plenum Publishing Corporation.
