Abstract
We examine structural, magnetic, and superconducting properties of magnetic/superconducting Ni/Nb multilayers. The Ni(Nb) films are textured {111}({110}) and have smooth interfaces. The average moment of the Ni atoms in the structure drops by 80% from that of bulk Ni for 19 Å thick Ni layers in proximity to 140 Å thick Nb layers, and goes to zero for smaller Ni thicknesses. The Nb layer is not superconducting for thicknesses <100 Å in the presence of a 19 Å thick ferromagnetic Ni layer. The behavior of the superconducting critical temperature as a function of the superconducting layer thickness was fitted and an interfacial scattering parameter and scattering time for the paramagnetic Ni regime determined.
