Making a Reconfigurable Artificial Crystal by Ordering Bistable Magnetic Nanowires

Spin-wave excitations (magnons) are investigated in a one-dimensional (1D) magnonic crystal fabricated out of Ni80Fe20 nanowires. We find two different magnon band structures depending on the magnetic ordering of neighboring wires, i.e., parallel and antip ...

Communication-based Swarming for Flying Robots

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert, Severin Leven

We aim at implementing a swarm of Micro-Air-Vehicles for creating communication networks (SMAVNETs) in disaster areas. For this purpose, we propose strategies for steering flying robots using only communication hardware (e.g. WiFi module or radio modem) an ...

Measurement of the magnetic field errors on TCV

Jean-Marc Moret, Francesco Piras, Jonathan Rossel

A set of 24 saddle loops is used on the Tokamak à Configuration Variable (TCV) to measure the radial magnetic flux at different toroidal and vertical positions. The new system is calibrated together with the standard magnetic diagnostics on TCV. Based on t ...

Magnetic correlations at graphene edges: Basis for novel spintronics devices

Oleg Yazyev

Magnetic zigzag edges of graphene are considered as a basis for novel spintronics devices despite the fact that no true long-range magnetic order is possible in one dimension. We study the transverse and longitudinal fluctuations of magnetic moments at zig ...

The role of the density gradient on intermittent cross-field transport events in a simple magnetized toroidal plasma

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Mario Ludovico Podesta, Francesca Maria Poli

Intermittent cross-field particle transport events (ITEs) are studied in the basic toroidal device TORPEX [TORoidal Plasma EXperiment, A. Fasoli et al., Phys. Plasmas 13, 055902 (2006)], with focus on the role of the density gradient. ITEs are due to the i ...

Transition from drift to interchange instabilities in an open magnetic field line configuration

Ambrogio Fasoli, Paolo Ricci, Mario Ludovico Podesta, Francesca Maria Poli

The transition from a regime dominated by drift instabilities to a regime dominated by pure interchange instabilities is investigated and characterized in the simple magnetized toroidal device TORPEX [TORoidal Plasma EXperiment, A. Fasoli et al., Phys. of ...

Magnetic crossover and complex excitation spectrum of the ferromagnetic/antiferromagnetic spin-1/2 chain system alpha-TeVO4

Helmuth Berger

We report magnetic-susceptibility, specific-heat, and Raman-scattering investigations of alpha-TeVO4 containing V-O edge-sharing chains. These chains promote a system of ferromagnetic/antiferromagnetic spin-1/2 Heisenberg alternating exchange chains with p ...

Spin-wave localization between nearest and next-nearest neighboring holes in an antidot lattice

Dirk Grundler

Broadband spectroscopy on spin waves is performed on a square Ni 80 Fe 20 antidot lattice with deep-submicron holes. Depending on the in-plane magnetic field H applied under different angles η , characteristic multiple resonances are resolved. Substantiate ...

Internal spin-wave confinement in magnetic nanowires due to zig-zag shaped magnetization

Dirk Grundler

We perform broadband spin-wave spectroscopy on thin submicrometer-wide Ni80Fe20 magnetic wires. Intentionally, we apply the in-plane magnetic field under an angle that is a few degrees off with respect to the in-plane hard-axis direction. In an intermediat ...
