Abstract

We study the proximity effect in superconductor $(S),$ antiferromagnetic (AF) bilayers, and report the fabrication and measurement of the first trilayer $S/\mathrm{AF}/S$ Josephson junctions. The disordered fcc alloy $\ensuremath{\gamma}\ensuremath{-}{\mathrm{Fe}}_{50}{\mathrm{Mn}}_{50}$ was used as the AF, and the S is Nb. Micron and submicron scale junctions were measured, and the scaling of ${J}_{C}{(d}_{\mathrm{AF}})$ gives a coherence length in the AF of 2.4 nm, which correlates with the coherence length due to suppression of ${T}_{C}$ in the bilayer samples. The diffusion constant for FeMn was found to be $1.7\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}{\mathrm{m}}^{2}{\mathrm{s}}^{\ensuremath{-}1},$ and the density of states at the Fermi level was also obtained. An exchange biased FeMn/Co bilayer confirms the AF nature of the FeMn in this thickness regime.
