+ | - The index of the layer. This index is used to reference its parameters in the script, e.g thickness[2] for the thickness value of layer 2. | ||
+ | - Thickness of the layer in Ångström | ||
+ | - Filename of the optical constants database files without ending (here Co.db, Cu.db, and vacuum.db). Files have to be in the same directory as the .all file. | ||
+ | - Optical constant delta, for the given energy (either from .db file or entered manually) | ||
+ | - Optical constant beta, same as delta | ||
+ | - Sigma, RMS roughness in Å between the layer and the one above! | ||
+ | - Magnetic delta, magneto optical constant (see remarks below) | ||
+ | - Magnetic beta, see magnetic delta | ||
+ | |||
+ | The example system is a multilayer consisting of 6x[ Co (10Å) / Cu (60Å)] on a Cu substrate. The optical constants provided correspond to a X-ray energy of 777eV and the .db filenames to the files shipped with this version of ReMagX (check the installation directory). | ||
+ | Remarks: | ||
+ | Delta (δ) and Beta (β) are the optical constants (dispersive and absorptive part) of the material according to the standard notation of a complex index of refraction: 𝑁=1−𝛿+𝑖β. | ||
+ | Sigma (σ) is the RMS roughness according to standard notation in surface science. | ||
+ | Magnetic delta (δm) and beta (βm) are the variation of the optical constants due to magnetism. | ||
