Abstract

A theoretical study of the proximity effect between superposed superconducting and itinerant electron antiferromagnetic films is presented. The model is based on the McMillan approach to a weakly coupled normal metal/superconductor bilayer. The spectra of one-particle excitations in the contacting films have been calculated and pronounced subgap features in the tunneling conductance of the bilayer are obtained. Implications of the present results for the antiferromagnetic metal/conventional superconductor junctions are discussed as well.
