Electron paramagnetic resonance of alkali metal atoms and dimers on ultrathin MgO
Stepan Kovarik, Roberto Robles, Richard Schlitz +4
Electron paramagnetic resonance (EPR) can provide unique insight into the chemical structure and magnetic properties of dopants in oxide and semiconducting materials that are of in…
Single 3 transition metal atoms on multi-layer graphene systems: electronic configurations, bonding mechanisms and role of the substrate
V. Sessi, S. Stepanow, A. N. Rudenko +8
The electronic configurations of Fe, Co, Ni, and Cu adatoms on graphene and graphite have been studied by x-ray magnetic circular dichroism and charge transfer multiplet theory. A…
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…
Element-resolved x-ray ferrimagnetic and ferromagnetic resonance spectroscopy
G. Boero, S. Mouaziz, S. Rusponi +4
We report on the measurement of element-specific magnetic resonance spectra at gigahertz frequencies using x-ray magnetic circular dichroism (XMCD). We investigate the ferrimagneti…
