Angular dependence of superconductivity in superconductor/spin-valve heterostructures

We report measurements of the superconducting transition temperature, Tc, in CoO/Co/Cu/Co/Nb multilayers as a function of the angle alpha between the magnetic moments of the Co layers. Our measurements reveal that Tc ( alpha ) is a nonmonotonic function, with a minimum near alpha = [pi]/2. Numerical...
