Spin dynamics of and impurities embedded in prototypical topological insulators
Juba Bouaziz, Manuel dos Santos Dias, Filipe Souza Mendes Guimarães +1
Topological insulators are insulating bulk materials hosting conducting surface states. Their magnetic doping breaks time-reversal symmetry and generates numerous interesting effec…
Universality of defect-skyrmion interaction profiles
Imara Lima Fernandes, Juba Bouaziz, Stefan Blügel +1
Magnetic skyrmions are prime candidates for future spintronic devices. However, incorporating them as an entity for information technology hinges on their interaction with defects…
Comparative study of methodologies to compute the intrinsic Gilbert damping: interrelations, validity and physical consequences
Filipe S. M. Guimarães, J. R. Suckert, Jonathan Chico +3
Relaxation effects are of primary importance in the description of magnetic excitations, leading to a myriad of methods addressing the phenomenological damping parameters. In this…
Impurity-induced orbital magnetization in a Rashba electron gas
Juba Bouaziz, Manuel dos Santos Dias, Filipe Souza Mendes Guimarães +2
We investigate the induced orbital magnetization density in a Rashba electron gas with magnetic impurities. Relying on classical electrodynamics, we obtain this quantity through th…
Ab initio investigation of impurity-induced in-gap states in BiTe and BiSe
Juba Bouaziz, Manuel dos Santos Dias, Julen Ibañez-Azpiroz +1
We investigate in-gap states emerging when a single transition metal impurity is embedded in topological insulators (BiTe and BiSe). We use a combined approach…
Spin-resolved inelastic electron scattering by spin waves in noncollinear magnets
Flaviano José dos Santos, Manuel dos Santos Dias, Filipe Souza Mendes Guimarães +2
Topological non-collinear magnetic phases of matter are at the heart of many proposals for future information nanotechnology, with novel device concepts based on ultra-thin films a…
