Abstract

By probing the magnetization profile of high-quality molecular-beam- epitaxy-grown Co/Cu(111) superlattices with spin-polarized neutron reflectivity (SPNR), we have observed a coherent antiferromagnetic spin structure and confirm that this coupling behavior sensitively depends on the Cu spacer thicknesses. We present magneto-optical Kerr-effect data from which the period of the exchange coupling can be determined to be about 9, consistent with theory and the SPNR data. With these results we confirm the existence of an oscillatory exchange coupling in this controversial system.
