A Trapped Field of >3T in Bulk MgB2 Fabricated by Uniaxial Hot Pressing
J. H. Durrell, C. E. J. Dancer, A. Dennis +7
A trapped field of over 3 T has been measured at 17.5 K in a magnetised stack of two disc-shaped bulk MgB2 superconductors of diameter 25 mm and thickness 5.4 mm. The bulk MgB2 sam…
Theory and experiment testing flux-line-cutting physics
John R. Clem, Marcus Weigand, J. H. Durrell +1
We discuss predictions of five proposed theories for the critical state of type-II superconductors accounting for both flux cutting and flux transport (depinning). The theories pre…
Practical vortex diodes from pinning enhanced YBa2Cu3O7-d
S. A. Harrington, J. L. MacManus-Driscoll, J. H. Durrell
We identify a scalable, practical route to fabricating a superconducting diode. The device relies for its function on the barrier to flux vortex entry being reduced at the substrat…
Suppression of vortex channeling in meandered YBa2Cu3O7-d grain boundaries
J. H. Durrell, D. M. Feldmann, C. Cantoni
We report on the in-plane magnetic field (H) dependence of the critical current density (Jc) in meandered and planar single grain boundaries (GBs) isolated in YBa2Cu3O7-d (YBCO) co…
Vortex deformation and breaking in superconductors: A microscopic description
E. Pardo, J. H. Durrell, M. G. Blamire
Vortex breaking has been traditionally studied for nonuniform critical current densities, although it may also appear due to nonuniform pinning force distributions. In this article…
Cross-over between channeling and pinning at twin boundaries in YBa2Cu3O7 thin films
A. Palau, J. H. Durrell, J. L. MacManus-Driscoll +5
The critical current (Jc) of highly twinned YBa2Cu3O7 films has been measured as a function of temperature, magnetic field and angle. For much of the parameter space we observe a s…
