Control of defect-mediated tunneling barrier heights in ultrathin MgO films
D. J. Kim, W. S. Choi, F. Schleicher +9
The impact of oxygen vacancies on local tunneling properties across rf-sputtered MgO thin films was investigated by optical absorption spectroscopy and conducting atomic force micr…
Lifetime of the surface magnetoplasmons in metallic nanoparticles
Guillaume Weick, Dietmar Weinmann
We study the influence of an external magnetic field on the collective electronic excitations in metallic nanoparticles. While the usual surface plasmon corresponding to the collec…
Euler buckling instability and enhanced current blockade in suspended single-electron transistors
Guillaume Weick, Felix von Oppen, Fabio Pistolesi
Single-electron transistors embedded in a suspended nanobeam or carbon nanotube may exhibit effects originating from the coupling of the electronic degrees of freedom to the mechan…
Exchange bias in GeMn nanocolumns: the role of surface oxidation
S. Tardif, S. Cherifi, M. Jamet +9
We report on the exchange biasing of self-assembled ferromagnetic GeMn nanocolumns by GeMn-oxide caps. The x-ray absorption spectroscopy analysis of this surface oxide shows a mult…
Imaging ferroelectric domains in multiferroics using a low-energy electron microscope in the mirror operation mode
Salia Cherifi, Riccardo Hertel, Stéphane Fusil +5
We report on low-energy electron microscopy imaging of ferroelectric domains with submicron resolution. Periodic strips of 'up' and 'down'-polarized ferroelectric domains in bismut…
Muon spin relaxation investigation of magnetic ordering in the hybrid organic-inorganic perovskites [(CH3)2NH2]M(HCOO)3, M = Ni,Co,Mn,Cu
P. J. Baker, T. Lancaster, I. Franke +6
Muon spin relaxation measurements are reported on samples of dimethylammonium metal formates containing magnetic divalent nickel, cobalt, manganese, and copper ions. These hybrid o…
Optical Probe of Quantum Shot Noise Reduction at a Single-Atom Contact
Natalia L. Schneider, Guillaume Schull, Richard Berndt
Visible and infra-red light emitted at a Ag-Ag(111) junction has been investigated from tunneling to single atom contact conditions with a scanning tunneling microscope. The light…
What is measured in the scanning gate microscopy of a quantum point contact?
Rodolfo A. Jalabert, Wojciech Szewc, Steven Tomsovic +1
The conductance change due to a local perturbation in a phase-coherent nanostructure is calculated. The general expressions to first and second order in the perturbation are applie…
Spin and charge dynamics in [TbPc] and [DyPc] single molecule magnets
F. Branzoli, P. Carretta, M. Filibian +5
Magnetization, AC susceptibility and SR measurements have been performed in neutral phthalocyaninato lanthanide ([LnPc) single molecule magnets in order to determine the…
Random barrier double-well model for resistive switching in tunnel barriers
Eric Bertin, David Halley, Yves Henry +6
The resistive switching phenomenon in MgO-based tunnel junctions is attributed to the effect of charged defects inside the barrier. The presence of electron traps in the MgO barrie…
Spin transfer in a ferromagnet-quantum dot and tunnel barrier coupled Aharonov-Bohm ring system with Rashba spin-orbit interactions
Xi Chen, Qing-Rong Zheng, Gang Su
The spin transfer effect in ferromagnet-quantum dot (insulator)-ferromagnet Aharonov-Bohm (AB) ring system with Rashba spin-orbit (SO) interactions is investigated by means of Keld…
Suppression of the Shastry-Sutherland phase in CePdSn at a field induced critical point
J. G. Sereni, M. Gomez Berisso, G. Schmerber +2
The magnetic phase diagram of CePdSn is investigated through the field dependence of thermal, transport and magnetic measurements performed at low temperature. The upper tr…
Level density of a Fermi gas and integer partitions: a Gumbel-like finite-size correction
Jérôme Roccia, Patricio Leboeuf
We investigate the many-body level density of gas of non-interacting fermions. We determine its behavior as a function of the temperature and the number of particles. As the temper…
