Substrate-Controlled Magnetism: Fe nanowires on vicinal Cu surfaces
Daniel Hashemi, Michael Waters, Valeriy S. Stepanyuk +2
Here we present a novel approach to control magnetic interactions in atomic-scale nanowires. Our ab initio calculations demonstrate the possibility to tune magnetic properties of F…
Ferromagnetism of Pd(001) substrate induced by Antiferromagnetic CoO
S. K. Saha, V. S. Stepanyuk, J. Kirschner
Our first-principles study has revealed unexpected spin polarization of the Pd(001) substrate in contact with antiferromagnetic CoO overlayers. We give an evidence that the ferroma…
Kondo effect in single atom contacts: the importance of the atomic geometry
Lucia Vitali, Robin Ohmann, Sebastian Stepanow +6
Co single atom junctions on copper surfaces are studied by scanning tunneling microscopy and ab-initio calculations. The Kondo temperature of single cobalt atoms on the Cu(111) sur…
Ab initio study of mirages and magnetic interactions in quantum corrals
V. S. Stepanyuk, L. Niebergall, W. Hergert +1
The state of the art ab initio calculations of quantum mirages,the spin-polarization of surface-state electrons and the exchange interaction between magnetic adatoms in Cu and Co c…
Long-range electronic interactions between adatoms on transition metal surfaces
V. S. Stepanyuk, L. Niebergall, A. N. Baranov +2
Ab initio calculations of surface-state mediated interactions between Cu adatoms on transition metal surfaces are presented. We concentrate on Co/Cu(111) and Co(0001) substrates an…
