Abstract

The authors have examined some of the magnetic properties of Cu-Mn alloys with Mn content in the range 0.16 to 3.75 wt.% to determine whether spin-glass effects could impair the performance of fine-filament Nb-Ti conductors. It appears that for Mn content in this range, the adverse magnetic properties of the matrix are not significant. Magnetization and susceptibility measurements show that adverse magnetic effects arising from spin-glass properties are minimal for concentrations of Mn up to at least 4%
