Abstract The use of resonant low-angle X-ray diffraction, combining specular and off-specular scans, has been used to characterize accurately and self-consistently the mesoscopic structure and the quality of interfaces for a set of magnetron sputtered Co/Cu multilayers. In addition, the use of a simulation program to fit experimental patterns, which is based on the Distorted Wave Born Approximation has permitted to confirm its validity in the region of total external reflection in a system having a high degree of complexity.

Conclusions Acknowledgements References Enlarge Image (14K) Fig. 1. Specular reflectivity patterns of Co/Cu multilayers recorded at an incident energy just under the Co absorption K-edge (7704 eV). Points correspond to the experimental patterns and solid lines have been calculated by the simulation program. Enlarge Image (11K) Fig. 2. Rocking curves taken at constant values of 2straight theta, small theta, Greek placed at a Kiessig maximum around 2straight theta, small theta, GreekM=1.32°. For the sake of clarity capital Delta, Greeksmall omega, Greek=small omega, Greek-straight theta, small theta, GreekM has been taken as the variable. The fits to the experimental patterns are based on the DWBA. The specular peak has not been reproduced in the simulations. Enlarge Image (11K) Fig. 3. 2straight theta, small theta, Greek-rock curves with their fit. The value of small omega, Greek was held constant and around 0.66°. The variable used is capital Delta, Greek2straight theta, small theta, Greek=2straight theta, small theta, Greek-2straight theta, small theta, GreekM. For the simulations only the diffuse intensity has been taken into account. Table 1. Values obtained by the fit procedure described in the text. From left to right, given values are: thickness of the Co layer, thickness of the Cu layer, Co r.m.s. roughness, Cu r.m.s. roughness, oxide layer thickness, oxide layer roughness, substrate roughness, horizontal correlation length, vertical correlation length and Hurst parameter View Table (<1K) References 1.
