Spin polarized secondary electrons; theory

We show that the spin polarization of the secondary electrons, P( E), yields useful information about the electron-electron interaction. The ratio of majority to minority spin lifetimes is related to the measured values of P( E) by τ↑( E)/ τ↓( E =[(1− p B )/(1+ p B)][(1+ P( E))/(1− P( E))], where p...

Summary:We show that the spin polarization of the secondary electrons, P( E), yields useful information about the electron-electron interaction. The ratio of majority to minority spin lifetimes is related to the measured values of P( E) by τ↑( E)/ τ↓( E =[(1− p B )/(1+ p B)][(1+ P( E))/(1− P( E))], where p B is the bulk magnetization.
