Palau, A and Dinner, R and Durrell, JH and Blamire, MG (2008) Vortex breaking and cutting in type II superconductors. Phys Rev Lett, 101. 097002-. ISSN 0031-9007Full text not available from this repository.
In technological superconductors, the Lorentz force on the flux vortices is opposed by inhomogeneous pinning and so the critical current may be controlled by a combination of vortex entanglement, cutting, and cross-joining. To understand the roles of these processes we report measurements of structures in which a weak pinning layer is sandwiched between two strongly pinning leads. Quantitative modeling of the results demonstrates that in such systems the critical current is limited by the deformation of individual vortices and not by subsequent cross-joining processes.
