Abstract
The effect of spin-up and spin-down exchange interaction on electron
acceleration by a surface plasma wave (SPW) propagating in magnetized
quantum plasma has been studied. The SPW was excited over the
metal–vacuum interface with maximum amplitude at the interface. The
effective dielectric constant was evaluated, considering the effects
of quantum Bohm potential, degenerate Fermi pressure, and electron
spin. The externally applied magnetic field perturbed the densities of
the oppositely spinning electrons, which resulted in spin
polarization. The dispersion relation and energy exchange mechanism
for the electron acceleration was built, incorporating the effects of
spin polarization in the wave–plasma interaction. The energy gain was
found to increase with the spin polarization.
