Open-Shell Molecules as Sensitive Probes of Spin-Orbit-Controlled Surface Electronic Structure
Solange Mariel Di Napoli, Alexei Nefedov, María Andrea Barral +5
Open-shell molecules are highly sensitive probes of correlated oxide surfaces because their partially occupied frontier orbitals strongly amplify subtle changes in adsorbate-substr…
Evidence for charge mediated coupling in Fe-Ga/PMN-PT composite multiferroic
M. Tortarolo, D. Goijman, M. A. Barral +11
We present an experimental study of the magnetoelectric coupling (MEC) in the Fe-Ga/PMN-PT thin film multiferroic composite by means of x-ray magnetic circular dichroism (XMCD) and…
Magnetic transition and spin-polarized two-dimensional electron gas controlled by polarization switching in strained CaMnO/BaTiO slabs
S. Di Napoli, A. Román, A. M. Llois +3
calculations show the presence of a strong magnetoelectric interfacial coupling in CaMnO ultra-thin film grown on a strained BaTiO ferroelectric film. This he…
Magnetic warping in topological insulators
Gabriele Naselli, Ali G. Moghaddam, Solange Di Napoli +4
We analyze the electronic structure of topological surface states in the family of magnetic topological insulators MnBiTe. We show that, at natural-cleavage surface…
Kondo physics in a Ni impurity embedded in O-doped Au chains
S. Di Napoli, M. A. Barral, P. Roura-Bas +3
By means of ab initio calculations we study the effect of O-doping of Au chains containing a nanocontact represented by a Ni atom as a magnetic impurity. In contrast to pure Au cha…
Non-Fermi liquid behaviour in non-equilibrium transport through Co doped Au chains connected to four-fold symmetric leads
S. Di Napoli, P. Roura-Bas, Andreas Weichselbaum +1
We calculate the differential conductance as a function of temperature and bias voltage, , through Au monoatomic chains with a substitutional Co atom as a magnetic impurity…
Magnetism- and impurity-assisted chain creation in Ir and Pt break junctions
Solange Di Napoli, Alexander Thiess, Stefan Blügel +1
Applying the generalization of the model for chain formation in break-junctions [JPCM 24, 135501 (2012)], we study the effect of light impurities on the energetics and elongation p…
Unusual Kondo physics in a Co impurity atom embedded in noble-metal chains
S. Di Napoli, M. A. Barral, P. Roura-Bas +3
We analyze the conduction bands of the one dimensional noble-metal chains that contain a Co magnetic impurity by means of ab initio calculations. We compare the results obtained fo…
Non-Fermi liquid behavior in transport through Co doped Au chains
S. Di Napoli, A. Weichselbaum, P. Roura-Bas +3
We calculate the conductance as a function of temperature through Au monoatomic chains containing one Co atom as a magnetic impurity, and connected to two conducting leads w…
Modelling impurity-assisted chain creation in noble-metal break junctions
Solange Di Napoli, Alexander Thiess, Stefan Blügel +1
In this work we present the generalization of the model for chain formation in break-junctions, introduced by Thiess {\it et al.} [\onlinecite{Alex08}], to zigzag transition-metal…
