19 Jun 2006 | Subject: | Mesoscopic Systems and Quantum Hall Effect; Materials Science | Abstract: | We study theoretically current-driven domain wall dynamics in (Ga,Mn)As. We show that the effective spin-orbit coupling of the holes qualitatively changes the domain wall dynamics and that standard spin transfer torque descriptions are inapplicable for (Ga,Mn)As. The strong effective spin-orbit coupling causes significant hole reflection from the domain wall, resulting in spin accumulation and mistracking between current-carrying spins and the domain wall magnetization. This strongly enhances the spin transfer torque and increases the current-driven domain wall mobility by four orders of magnitude, which is close to experimental findings. | Source: | arXiv, cond-mat/0606498 | Services: | Forum | Review | PDF | Favorites |
