The Influence of Ex Situ MgB2Barrier and HIP on the IcAnisotropy in Double Core MgB2/Cu Wires
2010
Acta Physica Polonica. A
The effect of large I c anisotropy reductions in MgB 2 /Cu sheathed wire is presented. The measurements of the critical current in rising magnetic field up to 14 T at 4.2 K were performed. Due to the application of the high isostatic pressure process to the copper sheathed MgB 2 wires with the ex situ MgB 2 homo barrier around the in situ core the anisotropy for such wires was very small and approached to less than 2% at magnetic field over 4 T. The presented geometry and technology show
