Abstract
We have used torque magnetometry to investigate the influence of magnetic spacer layers on the superconductivity in Nb/Co multilayers. Compared to similar systems which have nonmagnetic spacer layers, the samples exhibit two dimensional superconductivity for relatively thin magnetic layer thicknesses dCo, reflecting the effects of magnetic pair breaking. Moreover, the transition temperature to the superconducting state Tc shows a nonmonatonic dependence on dCo, which we examine within the framework of recent theories.
