Functionalized Bismuth Films: Giant Gap Quantum Spin Hall and Valley-Polarized Quantum Anomalous Hall States
Chengwang Niu, Gustav Bihlmayer, Hongbin Zhang +3
The search for new large band gap quantum spin Hall (QSH) and quantum anomalous Hall (QAH) insulators is critical for their realistic applications at room temperature. Here we pred…
Quantum well states and amplified spin-dependent Friedel oscillations in thin films
Mohammed Bouhassoune, Bernd Zimmermann, Phivos Mavropoulos +4
Electrons mediate many of the interactions between atoms in a solid. Their propagation in a material determines its thermal, electrical, optical, magnetic and transport properties.…
Spin transport and spin-caloric effects in (Cr,Zn)Te half-metallic nanostructures: Effect of spin disorder at elevated temperatures from first principles
Roman Kováčik, Phivos Mavropoulos, Stefan Blügel
An important contribution to the thermoelectric and spin-caloric transport properties in magnetic materials at elevated temperatures is the formation of a spin-disordered state due…
Spin-orbit torques in L1-FePt/Pt thin films driven by electrical and thermal currents
Guillaume Géranton, Frank Freimuth, Stefan Blügel +1
Using the linear response formalism for the spin-orbit torque (SOT) we compute from first principles the SOT in a system of two layers of L1-FePt(001) deposited on an fcc Pt(00…
First-principles analysis of a homo-chiral cycloidal magnetic structure in a monolayer Cr on W(110)
Bernd Zimmermann, Marcus Heide, Gustav Bihlmayer +1
The magnetic structure of a Cr monolayer on a W(110) substrate is investigated by means of first-principles calculations based on the noncollinear spin density functional theory (D…
Dzyaloshinskii-Moriya interaction and chiral magnetism in 3-5 zig-zag chains: Tight-binding model and ab initio calculations
Vikas Kashid, Timo Schena, Bernd Zimmermann +4
We investigate the chiral magnetic order in free-standing planar 3-5 bi-atomic metallic chains (3: Fe, Co; 5: Ir, Pt, Au) using first-principles calculations based on d…
