Hybrid FEM-analytical force and torque models of a reaction sphere actuator

This paper presents a hybrid FEM-analytical model for the magnetic flux density, the force and torque of a Reaction Sphere (RS) actuator for satellite attitude control. The RS is a permanent magnet synchronous spherical actuator whose rotor is magnetically ...

Kapellasite: A Kagome Quantum Spin Liquid with Competing Interactions

Magnetic susceptibility, NMR, muon spin relaxation, and inelastic neutron scattering measurements show that kapellasite, Cu3Zn(OH)(6)Cl-2, a geometrically frustrated spin-1/2 kagome antiferromagnet polymorphic with herbertsmithite, is a gapless spin liquid ...

Measurement of Tc distribution in NbSn CICC

Pierluigi Bruzzone, Davide Uglietti, Ciro Calzolaio

Knowledge of the actual Nb3Sn filaments' thermal strain, epsilon(th), in a cable-in-conduit conductor (CICC) is essential to predict the CICC performance in operation starting from the strand scaling laws for the critical current density J(c)(B, T, epsilon ...

Infrared phonon anomaly and magnetic excitations in single-crystal Cu3Bi(SeO3)(2)O2Cl

Helmuth Berger

Infrared reflection and transmission as a function of temperature have been measured on single crystals of Cu3Bi(SeO3)(2)O2Cl. The complex dielectric function and optical properties along all three principal axes of the orthorhombic cell were obtained via ...

Dipolar Antiferromagnetism and Quantum Criticality in LiErF4

Henrik Moodysson Rønnow, Gabriel Aeppli, Bastien Dalla Piazza, Julian Piatek, Neda Nikseresht Ghanepour, Nikolay Tsyrulin, Conradin Kraemer

Magnetism has been predicted to occur in systems in which dipolar interactions dominate exchange. We present neutron scattering, specific heat, and magnetic susceptibility data for LiErF4, establishing it as a model dipolar-coupled antiferromagnet with pla ...

Direct observation of a ferri-to-ferromagnetic transition in a fluoride-bridged 3d–4f molecular cluster

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

We report on the synthesis, crystal structure and magnetic characterisation of the trinuclear, fluoride-bridged, molecular nanomagnet [Dy(hfac)(3)(H2O)-CrF2(py)(4)-Dy(hfac)(3)(NO3)] (1) (hfacH = 1,1,1,5,5,5-hexafluoroacetylacetone, py = pyridine) and a clo ...

Interplay between the magnetic and electric degrees of freedom in multiferroic Co3TeO6

Helmuth Berger, Yang Zhao

Neutron diffraction, magnetic susceptibility, specific heat, and dielectric constant measurements of single-crystal Co3TeO6 have been measured to study the interplay between the ferroelectricity and magnetic order. Long-range incommensurate magnetic order ...

Dynamic saturation curve measurement for resin flow in glass fibre reinforcement

Véronique Michaud

A methodology is presented to determine the saturation curve of a resin/glass fabric system, during infiltration in a transparent mould under constant flow rate. Video acquisitions are transformed by image analysis into saturation level versus position and ...
