R. Hlubina et al., Screw dislocation-induced enhancement of the c-axis critical current in anisotropic superconductors, PHYSICA C, 329(1), 2000, pp. 5-11
Supercurrent in the weakly conducting c-axis direction of layered supercond
uctors is studied. It is shown that in the presence of screw dislocations w
ith Burgers vectors parallel to the c-axis, the critical current of small s
amples is enhanced with respect to the perfect crystal, each dislocation be
ing able to carry a supercurrent I-0. (C) 2000 Elsevier Science B.V. All ri
