Abstract
Measurements of the perpendicular upper critical magnetic field H-c21(T) ar e reported for several Nb/CuMn multilayers. It is found that, despite the m agnetic nature of the samples. the data for samples with low Mn percentage in the CuMn layers are simply described by the Werthamer-Helfand-Honenberg theory for conventional type-II superconductors, neglecting both Pauli spin paramagnetism and spin orbit impurity scattering. For high Mn concentratio n a different theoretical approach is needed.
