We report on hard and soft X-ray reflectivity investigations of (Ni_{80}Fe_{20} (2.2 nm)/Au(2.3 nm)/Co(0.8 nm)/Au(2.3 nm))_{10} multilayers. Specular reflectivity curves were measured with Cu K_{α} radiation and circularly polarized synchrotron radiation tuned to Co L_{3} and Ni L_{3} absorption edges. Structural properties of the multilayers were determined from the hard X-ray reflectivity curve. Comparison of reflectivity curves taken at different photon energies shows: (i) small difference in peak positions in dependence of reflectivity versus scattering vector q, (ii) different shapes of satellite Bragg peaks, (iii) different ranges of q for appearance of the Kiessig fringes. Analysis of soft X-ray reflectivity curves taken as a function of magnetic field allows to determine magnetic properties of Co and NiFe layer specifically.
