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…
Quantifying Exchange Forces of a Non-Collinear Magnetic Structure on the Atomic Scale
Nadine Hauptmann, Soumyajyoti Haldar, Tzu-Chao Hung +5
The large interest in chiral magnetic structures for realization of nanoscale magnetic storage or logic devices has necessitated methods which can quantify magnetic interactions at…
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…
