We report measurements of the superconducting transition temperature, T-c, in CoO/Co/Cu/Co/Nb multilayers as a function of the angle a between the magnetic moments of the Co layers. Our measurements reveal that T-c(alpha) is a nonmonotonic function, with a minimum near alpha = pi/2. Numerical self- consistent solutions of the Bogoliubov-de Gennes equations quantitatively and accurately describe the behavior of T-c as a function of alpha and layer thicknesses in these superconductor/spin-valve heterostructures. We show that experimental data and theoretical evidence agree in relating T-c (alpha) to enhanced penetration of the triplet component of the condensate into the Co/Cu/Co spin valve in the maximally noncollinear magnetic configuration.
