Phonon-Induced Spin Relaxation of Conduction Electrons in Aluminum

Spin-flip Eliashberg function ${\alpha }_S^{2}F$ and temperature-dependent spin relaxation time $T_1\left(T\right)$ are calculated for aluminum using realistic pseudopotentials. The spin-flip electron-phonon coupling constant ${\lambda }_S$ is found to be $2.5\times {10}^{-5\mathrm{}}$. The calculations agree with experiments validating the Elliott-Yafet theory and the spin-hot-spot picture of spin relaxation for polyvalent metals.
