Abstract
We report on hard and soft X-ray reflectivity investigations of (Ni80Fe20(2.2 nm)/Au(2.3 nm)/Co(0.8 nm)/Au(2.3 nm))10 multilayers. Specular reflectivity curves were measured with Cu Kα radiationand circularly polarized synchrotron radiation tuned to Co L3 and Ni L3 absorption edges. Structural propertiesof 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.
