Abstract
We have performed reflectance and EELS measurements on the quaternary superconductor YNi2B2C. Linking together the results of these two types of experiments we derived the dielectric function in the energy range between 10 meV and 50 eV. The data were analysed by using a generalized Drude-Lorentz model, where retardation effects resulting from the electron-phonon interaction were taken into account to describe the free-carrier response. For the d.c. coupling constant a value of λtr ~ 1.2 was obtained.Keywords
