Cobalt/rhenium multilayers were prepared by rf and dc sputtering and studied using RBS and hyperfine interaction techniques. The layer thickness is determined with a precision of 3 angstrom, and the interface intermixing is less than 5 angstrom up to 773 K. Solid state reactions occur for higher temperatures. The hyperfine field value confirms the hcp structure of the Co. A small shift of the hyperfine field measured as function of the cobalt layer thickness is explained by the effect of lattice stresses.
