Schematic picture of the double proximity effect in SC/QM/FM structure. refers to the injected Cooper pair density, while represents the induced magnetic moment.
SAXS spectra for a set of multilayers with varying Pd thickness (see Table I). A Bragg peak is still detectable even for a very thin Pd layer, . Inset: SAXS from a multilayer. In the latter case no sharp features are distinguishable.
Superconducting critical temperature vs for the samples described in the text. Inset: magnetic moment at saturation vs for bilayers. The connecting lines are just a guide for the eyes.
(a) Left axis: magnetic moment per Fe atom vs . The open triangles refer to the SFe1 samples, while the closed triangles include the contribution from the Pd layer (SFe2). Right axis. vs for the SFe1 and SFe2 sample sets (open, closed circles, respectively). The connecting lines are just a guide for the eye. (b) vs for the sample SFe1 (open circles) and (filled circles) for the SFe2 set. The lines are data interpolation according to the model of Ref. 1. For SFe2, the bilayer was assumed as one single FM.
Summary of the structure of the samples. In each layer sequence, the layer thickness denoted as is the one that is being varied. The layer thicknesses are given in Å. Some samples are capped with a Nb layer—this is too thin to be superconducting and plays no active role in the sample properties. The substrate is Si(100) for all the samples.
