Abstract

Composition modulated (with wavelengths between 1.6 to 4.98 nm) Cu/NiFe ternary alloy thin films containing 53 at % Cu, 40 at % Ni, and 7 at % Fe were prdduced by the vapor-phase growth technique. The inter-diffusivities in these films were measured at temperatures 320°C, 345°C, and 400°C from the growth or decay rate of satelite peak intensities. as a function of dispersion relation B2 exhibited anomalous behavior at certain wavelengths at which an enhanced elastic modulus effect is also observed. This anomalous behavior was directly attributed to the long range interaction.
