Magnetic properties of Co doped Nb clusters
A. Diaz-Bachs, L. Peters, R. Logemann +4
From magnetic deflection experiments on isolated Co doped Nb clusters we made the interesting observation of some clusters being magnetic, while others appear to be non-magnetic. T…
Exchange interactions in transition metal oxides: The role of oxygen spin polarization
R. Logemann, A. N. Rudenko, M. I. Katsnelson +1
Magnetism of transition metal (TM) oxides is usually described in terms of the Heisenberg model, with orientation-independent interactions between the spins. However, the applicabi…
Geometric, electronic and magnetic structure of FeO clusters
R. Logemann, G. A. de Wijs, M. I. Katsnelson +1
Correlation between geometry, electronic structure and magnetism of solids is both intriguing and elusive. This is particularly strongly manifested in small clusters, where a vast…
Modeling Klein tunneling and caustics of electron waves in graphene
R. Logemann, K. J. A. Reijnders, T. Tudorovskiy +2
We employ the tight-binding propagation method to study Klein tunneling and quantum interference in large graphene systems. With this efficient numerical scheme, we model the propa…
