Abstract
We determine gamma-terms and Debye temperatures Theta(D) (T) on ordere d and disordered Fe100-xPtx (x = 26-30 at %). Both quantities are inde pendent of x. Enhancement of gamma with respect to theoretical DOS can be related to electron-phonon coupling, consistent with phonon soften ing observed with decreasing T in neutron spectra. This property also explains the decrease of Theta(D) (T) for T --> 0.
