Self-Assembled Nanometer-Scale Magnetic Networks on Surfaces: Fundamental Interactions and Functional Properties

Klaus Kern, Harald Brune, Stefano Rusponi, Pietro Gambardella, Anne Lehnert, Sergio Vlaic, Sebastian Stepanow

Nanomagnets of controlled size, organized into regular patterns open new perspectives in the fields of nanoelectronics, spintronics, and quantum computation. Self-assembling processes on various types of substrates allow designing fine-structured architect ...

Matching Pursuit Iterative Dipole Based Filter of Background Fields in Phase Imaging

Rolf Gruetter, Yves Wiaux, José Pedro Rebelo Ferreira Marques

The information present in the phase of gradient-echo images has opened a new window to look at fine brain anatomy. To obtain high quality phase images depicting small field perturbations produced by tissue susceptibility differences, large slowly spatiall ...

Optically Erasing Disorder in Semiconductor Microcavities with Dynamic Nuclear Polarization

Vincenzo Savona, Timothy Chi Hin Liew

The mean squared value of the photonic disorder is found to be reduced by a factor of 100 in a typical GaAs based microcavity when exposed to a circularly polarized continuous wave optical pump without any special spatial patterning. Resonant excitation of ...

Unusual Rydberg System Consisting of a Positively Charged Helium Nanodroplet with an Orbiting Electron

Marcel Drabbels, Evgeniy Loginov

Evidence is presented of an unusual Rydberg system consisting of a helium nanodroplet containing a positively charged sodium ion and an orbiting electron. Rydberg states of this system with principal quantum number n

Dynamics of individual rotational states in an electrostatic guide for neutral molecules

Andreas Osterwalder, Benjamin Bertsche

The guiding properties of individual rotational states of deuterated ammonia inside an electrostatic hexapole guide are presented. The guide is combined with resonance enhanced multiphoton ionization detection to assess the guiding probabilities and veloci ...

Magnonic minibands in antidot lattices with large spin-wave propagation velocities

Dirk Grundler

Antidot lattices fabricated from permalloy thin films have been investigated by all-electrical spin-wave spectroscopy and Brillouin light scattering. Periodic arrays of 120-nm-diameter nanoholes have been prepared using focused ion beam etching. The period ...

Four-electron oxygen reduction by Tetrathiafulvalene

Hubert Girault, Astrid Johana Olaya Avendano, Péter Kalman Péchy, Jérôme Florian Gonthier, Peiyu Ge

The four-electron reduction of oxygen by tetrathiafulvalene (TTF) in acidified 1,2-dichloroethane and at the acidified water/1,2-dichloroethane interface has been observed. Spectroscopy and ion transfer voltammetry results suggest that the reaction proceed ...

A tunable two-impurity Kondo system in an atomic point contact

Klaus Kern, Peter Wahl

Two magnetic atoms, one attached to the tip of a scanning tunnelling microscope and one adsorbed on a metal surface, each constituting a Kondo system, have been proposed as one of the simplest conceivable systems potentially exhibiting quantum critical beh ...

Magnetic phase diagram of the antiferromagnetic cobalt tellurate Co3TeO6

Helmuth Berger, Wei Li

In this study, we measured the temperature-dependent magnetic susceptibility [chi(T)], ac magnetic susceptibility [chi(ac)(T)], specific heat [C-p(T)], and high-field magnetization [M(H)] of a newly synthesized single-crystalline material, Co3TeO6. Two tra ...

Density of states deduced from ESR measurements on low-dimensional nanostructures; benchmarks to identify the ESR signals of graphene and SWCNTs

László Forró, Péter Szirmai, Ferenc Simon

Electron spin resonance (ESR) spectroscopy is an important tool to characterize the ground state of conduction electrons and to measure their spin-relaxation times. Observing ESR of the itinerant electrons is thus of great importance in graphene and in sin ...
