Query: Giant current-driven domain wall mobility in (Ga,Mn)As   We study theoretically hole current-driven domain wall dynamics in (Ga,Mn)As.
We show that the spin-orbit coupling causes significant hole reflection at the
domain wall, even in the adiabatic limit when the wall is much thicker than the
Fermi wavelength, resulting in spin accumulation and mistracking between
current-carrying spins and the domain wall magnetization. This increases the
out-of-plane non-adiabatic spin transfer torque and consequently the
current-driven domain wall mobility by three to four orders of magnitude.
Trends and magnitude of the calculated domain wall current mobilities agree
with experimental findings.
