Abstract : The results of the research conducted during the first year of this program (12/90 - 8/91) are summarized below: (a) An electrodeposition system has been assembled which is capable of producing high quality multilayered thin films. (b) Cu-Ni multilayered films with bilayer repeat lengths of 2.5 and 22 nm have been produced. (c) These films have displayed unusually large damping capacity over the frequency range 0.1 to 10 Hz, compared to typical metallic behavior.
