Design of spin-orbital-textures in ferromagnetic/topological insulator interfaces
A. L. Araújo, F. Crasto de Lima, C. H. Lewenkopf +1
Spin-orbital textures in topological insulators due to the spin locking with the electron momentum, play an important role in spintronic phenomena that arise from the interplay bet…
DFT2kp: effective kp models from ab-initio data
João Victor V. Cassiano, Augusto L. Araújo, Paulo E. Faria Junior +1
The method, combined with group theory, is an efficient approach to obtain the low energy effective Hamiltonians of crystalline materials. Although the…
Fabry-Pérot resonant vortices and magnetoconductance in topological insulator constrictions with magnetic barriers
R. P. Maciel, A. L. Araújo, C. H. Lewenkopf +1
The edge states of two-dimensional time-reversal topological insulators support a perfect helical conductance on wide ribbons due to the absence of backscattering. Here, we study t…
Driven energy transfer between coupled modes in spin-torque oscillators
R. Lebrun, J. Grollier, P. Bortolotti +11
The mutual interaction between the different eigenmodes of a spin-torque oscillator can lead to a large variety of physical mechanisms from mode hopping to multi-mode generation, t…
Topological Nonsymmorphic Ribbons out of Symmorphic Bulk
Augusto L. Araújo, Ernesto O. Wrasse, Gerson J. Ferreira +1
States of matter with nontrivial topology have been classified by their bulk symmetry properties. However, by cutting the topological insulator into ribbons, the symmetry of the sy…
