Interdiffusion in epitaxial Co/Pt multilayers Academic Article

abstract

• Interdiffusion kinetics were measured using x-ray diffraction methods in epitaxial (001) and (111) Co/Pt multilayers in which the chemical modulation wavelength was in the range 2.54.0 nm. Multilayers were prepared by e-beam evaporation and were subsequently annealed in vacuum at temperatures between 275 and 375C. The activation enthalpy of the interdiffusion process in this temperature range was estimated using a novel approach for scaling nonlinear diffusion data. Activation enthalpies for interdiffusion in (001) and (111) multilayers were determined to be 1.10.2 and 0.80.2 eV, respectively. The low values obtained for the activation enthalpies may result from coherency strains or short-circuit diffusion in the faulted, epitaxial multilayers.
