Abstract The X-ray reflectivity technique was used to study the annealing effect on layer structure of Ta/FeMn/NiFe/Cu/NiFe/Ta multilayer thin films on Si substrates. High-resolution specular reflectivity data were collected and analyzed by least-squares refinement. Results on layer thickness, density and roughness were obtained and correlated with the magnetic properties of the films.
