A hybrid model for estimation of pore size from ortho-positronium lifetimes in porous materials
L. Anh Tuyen, T. Dong Xuan, H. A. Tuan Kiet +11
The present paper proposes a novel model for estimating the free-volume size of porous materials based on the analysis of various experimental ortho-positronium (-Ps) lifetime d…
Non-local field-like spin-orbit torques in Rashba systems: an ab-initio study of AgBi/Ag/Fe film
Guillaume Géranton, Bernd Zimmermann, Nguyen H. Long +4
We investigate from first principles the field-like spin-orbit torques (SOTs) in a AgBi-terminated Ag(111) film grown on ferromagnetic Fe(110). We find that a large part of t…
Influence of complex disorder on skew-scattering Hall effects in -ordered FePt alloy
Bernd Zimmermann, Nguyen H. Long, Phivos Mavropoulos +2
We show by first-principles calculations that the skew-scattering anomalous Hall and spin-Hall angles of L-ordered FePt drastically depend on different types of disorder. A di…
Strong spin-orbit fields and Dyakonov-Perel spin dephasing in supported metallic films
Nguyen H. Long, Phivos Mavropoulos, David S. G. Bauer +3
Spin dephasing by the Dyakonov-Perel mechanism in metallic films deposited on insulating substrates is revealed, and quantitatively examined by means of density functional calculat…
Giant spin Nernst effect induced by resonant scattering at surfaces of metallic films
Nguyen H. Long, Phivos Mavropoulos, Bernd Zimmermann +2
A new concept realizing giant spin Nernst effect in nonmagnetic metallic films is introduced. It is based on the idea of engineering an asymmetric energy dependence of the longitud…
Mesoscopic electron focusing in topological insulators
P. Sessi, P. Rüßmann, T. Bathon +15
The particle wave duality sets a fundamental correspondence between optics and quantum mechanics. Within this framework, the propagation of quasiparticles can give rise to superpos…
