Abstract
Calculations of the Gilbert damping parameter alpha for bulk Ni are presented
as a function of the spin-dependent Lorentzian broadening of the one-electron states. The
Kambersky formula for alpha is used, correctly restricted to second order in the spin-orbit
parameter so that intra band terms are suppressed, and the spin-dependent broadening is
deduced from the recent calculations of electron lifetimes due to electron-phonon scattering
by Carva et al. The calculated value of alpha for Ni at room temperature is in reasonable
agreement with experiment.
