Quantum Anomalous Hall Effect and Anderson Chern Insulating Regime in Noncollinear Antiferromagnetic 3Q State
Papa Bireme Ndiaye, Adel Abbout, Aurelien Manchon
We investigate the emergence of both quantum anomalous Hall and disorder-induced Anderson Chern insulating phases in two dimensional hexagonal lattices, with antiferromagnetically…
Intrinsic non-adiabatic topological torque in magnetic skyrmions and vortices
Collins Ashu Akosa, Papa Birame Ndiaye, Aurélien Manchon
We propose that topological spin currents flowing in topologically non-trivial magnetic textures, such as magnetic skyrmions and vortices, produce an intrinsic non-adiabatic torque…
Topological Hall and Spin Hall Effects in Disordered Skyrmionic Textures
P. B. N'diaye, C. A. Akosa, A. Manchon
We carry out a throughout study of the topological Hall and topological spin Hall effects in disordered skyrmionic systems: the dimensionless (spin) Hall angles are evaluated acros…
Dirac Spin-Orbit Torques at the Surface of Topological Insulators
P. B. Ndiaye, C. A. Akosa, M. H. Fischer +3
We address the nature of spin-orbit torques at the magnetic surfaces of topological insulators, using both Kubo formula and Keldysh formalism. Through the analysis of the derived s…
Magnon-Mediated Dzyaloshinskii-Moriya Torque in Homogeneous Ferromagnets
Aurelien Manchon, P. Birame Ndiaye, Jung-Hwan Moon +2
In thin magnetic layers with structural inversion asymmetry and spin-orbit coupling, a Dzyaloshinskii-Moriya interaction arises at the interface. When a spin wave current ${\bf j}_…
