Spin Orbit Torque in two dimensional Antiferromagnetic Topological Insulators | | Sumit Ghosh

5 Sep 2016 | | Abstract: | We investigate spin transport in two dimensional ferromagnetic (FTI) and
antiferromagnetic (AFTI) topological insulators. Contrary to FTI, AFTI supports
zero energy modes in presence of an in plane magnetic order, which enables
topologically protected edge conduction at low energy. We also address the
nature of current-driven spin torque in these structures and study the impact
of spin-independent disorder. Interestingly, upon strong disorder the spin
torque develops an enhanced staggered antidamping component (i.e. even in
magnetization direction), which enables current- driven manipulation of the
antiferromagnetic order parameter. We also show that the staggered torque
decreases when the system enters the trivial insulator regime, denoting its
topological origin. | | Source: | arXiv, 1609.1174 | | Services: | Forum | Review | PDF | Favorites | |
