Abstract
Epitaxially grown multilayer systems offer the possibility to study the influence of ferromagnetism on superconductivity in a controlled way. In this paper, we explore how the superconducting properties of high quality epitaxially grown superconductor/normal-metal/ferromagnet trilayers evolve as a function of the exchange splitting in the ferromagnet and the thickness of the normal-metal layer. We report results for Nb(110)/Au(111)/Co(0001) and make a detailed comparison with earlier results for Nb(110)/Au(111)/Fe(110). We use quantitative fast Fourier transform analysis to confirm the existence of a long-period (2.1 nm) oscillation in the superconducting transition temperature Tc as a function of the Au-layer thickness tAu for tAu>2 nm and highlight an additional short-period (0.76 nm) oscillation for tAu
