Hysteresis in a Fine Filament NbTi Composite

Modeling of Proximity Coupling between Superconducting Filaments in Superconducting Dipole Magnets

“…(7a) (7b) (8) (8a) or zero, whichever is larger. The expression given in 8a does not predict the onset of proximity coupling very well, but it is useful in the region where Ms2 becomes important to the total magnetization.l2 Figure 2 shows magnetization curves generated by the SCMAG04 code for a conductor which exhibits proximity coupling between filaments.…”
