Conventional deuterium contrast variation neutron reflectometry (NR) sometimes misleads when the deuterated SIMULATION samples fail to reproduce the structure of the REAL ones by delicate techniques such as spin-coating. On the other hand, the Spin contrast variation (SCV)-NR determines the structure from PH-dependent NR profiles of REAL samples. Therefore, the SCV-NR works not only as a technique which omits the cost of deuterium substitution, but also as a reliable technique to determine multi-layered surface and interface structure.
