Ly. Zhang et al., THE EFFECT OF THE ELECTRON-PHONON INTERACTION ON GIANT MAGNETORESISTANCE IN MAGNETIC MULTILAYERS, Communications in Theoretical Physics, 27(2), 1997, pp. 129-134
We built electron and phonon free energies and attempted to investigat
e the effect of the electron-phonon interaction on giant magnetoresist
ance in magnetic multilayers. Starting from a jellium-like model, we f
ound that the electron-phonon interaction can have an important effect
on the spin splitting of electronic energy band. The expression of gi
ant magnetoresistance has been obtained by considering the spin splitt
ing of electronic energy band, indicating that the effect of phonon co
uld not be neglected. Numerical calculations using our approach demons
trate the agreement between experimental and theoretical values.
