Topological and spin-orbit effects on orbital moments in ultra-thin magnetic films
Felix Nickel, Soumyajyoti Haldar, Mara Gutzeit +1
Topological orbital moments (TOMs) are a direct hallmark of a magnetic texture with a non-trivial spin topology. In addition to giving insight into the topology of the magnetic tex…
Bilayer triple-Q state driven by interlayer higher-order exchange interactions
Bjarne Beyer, Mara Gutzeit, Tim Drevelow +3
Using first-principles calculations and an atomistic spin model we predict the stabilization of a bilayer triple-Q state in an atomic Mn bilayer on Ir(111) due to interlayer higher…
Trends of higher-order exchange interactions in transition-metal trilayers
Mara Gutzeit, Soumyajyoti Haldar, Sebastian Meyer +1
We present a systematic study of higher-order exchange interactions beyond the pair-wise Heisenberg exchange in transition-metal trilayers based on density functional theory calcul…
Electronic and magnetic properties of 3 transition-metal adatoms on Mn/W(110)
Mara Gutzeit, Soumyajyoti Haldar, Stefan Heinze
Using density functional theory, we investigate the electronic and magnetic properties of transition-metal adatoms adsorbed on a monolayer of Mn on W(110). Mn/W(110) has a non…
Tunneling anisotropic magnetoresistance of Pb and Bi adatoms and dimers on Mn/W(110): A first-principles study
Soumyajyoti Haldar, Mara Gutzeit, Stefan Heinze
We show that Pb and Bi adatoms and dimers have a large tunneling anisotropic magnetoresistance (TAMR) of up to 60% when adsorbed on a magnetic transition-metal surface due to stron…
