Abstract In order to investigate interdiffusion in Mo/V multilayers, we present a method that combines both kinetic mean-field simulations and calculations of x-ray scattered intensity with disorder effects. Considering preliminary experimental data obtained on Mo(4nm)/V(2nm) multilayers, we show that the angular shift of spectra observed after annealing, should take place for both Fickian and asymmetric interdiffusion modes. In contrast, clear signatures of the interdiffusion modes are found from the simulation of the peak intensities. These results offer interesting perspectives for a full analysis of the interdiffusion in these systems.
