摘要：
We apply our first-principles SDFA-RPA scheme to calculate the spin fluctuation spectrum as well as the phonon and the spin fluctuation Eliashberg functions of the lightest rare earth metal scandium. These quantities are used to evaluate the low-temperature electron mass enhancement. We find that both terms are sizeable. Together with our calculated bandstructure densities of states at the Fermi energy, our results are compatible with experimental data for the low-temperature specific heat coefficient.
