  • Individual grain boundary properties and overall performance of metal-organic deposition coated conductors 

    Weigand, M; Speller, SC; Hughes, GM; Rutter, Noel Antony; Grovenor, CRM; Durrell, John Hay (2010)
    We have investigated single grain boundaries (GBs) isolated in coated conductors produced by metal-organic deposition. When a magnetic field is swept in the film plane, an angle-dependent crossover from boundary to grain ...
  • Practical vortex diodes from pinning enhanced YBa2Cu3O7-delta 

    Harrington, Sophie-Ann; MacManus Driscoll, JL; Durrell, John Hay (2009)
    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 substrate interface of a superconducting pinning enhanced ...
  • Importance of low-angle grain boundaries in YBa2Cu3O7-delta coated conductors 

    Durrell, John Hay; Rutter, Noel Antony (Institute of Physics Publishing, 2009)
    Over the past ten years the perception of grain boundaries in YBa2Cu3O7-δ conductors has changed greatly. They are no longer a problem to be eliminated but an inevitable and potentially favourable part of the material. ...
  • Benefits of current percolation in superconducting coated conductors 

    Rutter, Noel Antony; Durrell, John Hay; Blamire, Mark Giffard; Macmanus Driscoll, JL; Wang, H; Foltyn, SR (2005)
    The critical currents of MOD/RABiTS and PLD/IBAD coated conductors have been measured as a function of magnetic field orientation and compared to films grown on single crystal substrates. By varying the orientation of ...
