Scattering of neutrons against protons remarkably depends on relative direction of their spins. Spin contrast variation is a technique to determine structure of composite materials using the polarization-dependent neutron scattering against proton. Recently, we have developed the first SCV neutron reflectivity technique for structural analysis of multilayer films. Structure of multilayer films can be determined from the proton-polarization dependent polarized neutron scatterings.
