Magnetic quadrupolar order in the chiral square cupola compound BaTiOCu4(PO4)4

Henrik Moodysson Rønnow, Luc Testa, Peter Babkevich, Gregory Scott Tucker

We report neutron diffraction studies of the magnetic structure in BaTiOCu4(PO4)4 , which is a newly discovered magneticinsulator crystallizing in a tetragonal chiral crystal structure with P4212 space group [1]. The crystal structure ischaracterized by an ...

Complex magnetic incommensurability and electronic charge transfer through the ferroelectric transition in multiferroic Co3TeO6

Helmuth Berger, Yang Zhao

Polarized and unpolarized neutron diffractions have been carried out to investigate the nature of the magnetic structures and transitions in monoclinic Co3TeO6. As the temperature is lowered below 26 K long range order develops, which is fully incommensura ...

Estimation of the centre of mass kinematics in alpine ski racing using inertial and magnetic sensors

Kamiar Aminian, Benedikt Fasel

For performance analysis in alpine ski racing, an accurate and precise estimation of the centre of mass (CoM) kinematics is indispensable. Currently available systems satisfying this need are video-based stereo-photogrammetry or differential global navigat ...

Anomaly detection in elderly daily behavior in ambient sensing environments

Daniel Gatica-Perez, Oya Aran, Dairazalia Sanchez Cortes

Current ubiquitous computing applications for smart homes aim to enhance people’s daily living respecting age span. Among the target groups of people, elderly are a population eager for “choices for living arrangements”, which would allow them to continue ...

Magnetic remanence in single atoms

Harald Brune, François Patthey, Stefano Rusponi, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Zeljko Sljivancanin, Aparajita Singha, Romana Baltic, Katharina Johanna Diller, Edgar Fernandes

A permanent magnet retains a substantial fraction of its saturation magnetization in the absence of an external magnetic field. Realizing magnetic remanence in a single atom allows for storing and processing information in the smallest unit of matter. We s ...

Direct observation of anisotropic magnetic field response of the spin helix in FeGe thin films

Henrik Moodysson Rønnow, Jonathan White

We report the observation by small-angle neutron scattering (SANS) of a magnetic helical structure confined in a thin film of the chiral lattice magnet FeGe. Twofold magnetic Bragg spots appearing below the magnetic transition temperature indicate the form ...

Detection of Pressure or Flow Rate Variations in MR Valves through Magnetic Flux Analysis

Yves Perriard, Yoan René Cyrille Civet, Daniel Grivon

Magneto-Rheological (MR) fluids consist in a suspension of ferromagnetic particles dispersed in a fluid carrier. If excited by a magnetic source, the nearby magnetic field induces the particles magnetization with the formation of chainlike structures align ...

Structural, electrical and magnetic characterization of in-situ crystallized ZnO:Co thin films synthesized by reactive magnetron sputtering

Andreas Schueler

Zn1-xCoxO (0 < x < 0.146) conductive thin films have been deposited by reactive magnetron sputtering of metallic Zn and Co targets at high pressure and temperature. The structural properties have been investigated by using X-ray diffraction (XRD) and X-ray ...

Interaction between the Lower Hybrid wave and density fluctuations in the scrape-off layer

Joan Decker

In the present paper, the perturbation of the launched power spectrum of the Lower Hybrid wave at the separatrix by electron density fluctuations in the scrape-off layer is investigated. Considering a slab geometry with magnetic field lines parallel to the ...
