Resistivity and electron-phonon coupling in YNi2B2C single crystals

In this work, we present the results of precise measurements of the resisti vity of YNi2B2C single crystals with T-c = 15.5 Ii as a function of the tem perature, and analyze the experimental data in the framework of the Bloch-G runeisen theory and electron-phonon, coupling. The transport electron-phono n spectral function that best fits the resistivity data is then inserted in the real-axis Eliashberg equations, which are: directly solved to determin e the normalized tunneling conductance both ii, s- and d-wave symmetry.
