PROXIMITY-INDUCED SUPERCONDUCTIVITY IN AN ANTIFERROMAGNETIC EXCHANGE FIELD

A theoretical study of the proximity effect between superposed superco nducting 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 fe atures in the tunneling conductance of the bilayer are obtained. Impli cations of the present results for the antiferromagnetic metal/convent ional superconductor junctions are discussed as well.
