Considerations on critical currents and stability of MgB2 wires made by different preparation routes

Adiabatic Normal Zone Development in<tex>$rm MgB_2$</tex>Superconductors

“…In order to demonstrate the effect of the n-value on the normal zone propagation, we used and data measured on a conductor by Goldacker et al [10]. Although these conductors have a very good performance, they have a rather low n-value of about 15.…”

Superconducting materials for large scale applications

“…A particularly rapid use of MgB wire has been for low thermal conductivity current leads in the ASTRA-2 satellite [91]. However, it is clear from analyses of the electrical resistivity of many samples, including wires, that bulk MgB is actually very far from being fully sintered or electrically connected [33].…”

Relation between Current Transfer Length and Stability of Fe/MgB2and Fe/Nb/MgB2Conductors

“…Building any specific application such as power cables or superconducting magnets requires research of its basic element from which the device is constructed -superconducting composite conductor. Recently found superconductivity in MgB 2 [1] attracts many research groups to investigate stability of composite conductors based on this material [2][3][4]. Optimizing and improving conductor properties e.g.…”
