Observations of Pauli paramagnetic effects on the flux line lattice in CeCoIn5

Sandrine Gerber, Joël Mesot, Jonathan White, Pratyush Das

From small-angle neutron scattering studies of the flux line lattice (FLL) in CeCoIn5, with magnetic field applied parallel to the crystal c-axis, we obtain the field and temperature dependence of the FLL form factor (FF), which is a measure of the spatial ...

Muon spin relaxation study of the layered magnetoelectric FeTe2O5Br with spin amplitude modulated magnetic structure

Helmuth Berger

Local-probe weak-transverse-field and zero-field mu SR measurements have been employed to investigate magnetic ordering in the new magnetoelectric compound FeTe2O5Br. Below the Neel transition temperature T-N=10.6 K a static local magnetic field starts to ...

Two-dimensional square-lattice S=1/2 antiferromagnet Cu(pz)(2)(ClO4)(2)

Henrik Moodysson Rønnow, Nikolay Tsyrulin

We present an experimental study of the two-dimensional S=1/2 square-lattice antiferromagnet Cu(pz)(2)(ClO4)(2) (pz denotes pyrazine-C4H4N2) using specific-heat measurements, neutron diffraction, and cold-neutron spectroscopy. The magnetic field dependence ...

Drift stabilization of ballooning modes in a high-$\langle \beta \rangle$ LHD configuration

Jonathan Graves, Wilfred Anthony Cooper, Lucie Brocher

Ideal MHD yields at best inconclusive predictions about the stability of the LHD heliotron for

\langle \beta \rangle \geq 3\%

. We investigate the impact of the drift stabilization of ballooning modes for the inward shifted LHD configuration (vacuum magne ...

Multifrequency ESR in ET2 MnCu[N(CN)(2)](4): A radical cation salt with quasi-two-dimensional magnetic layers in a three-dimensional polymeric structure

László Forró, Bálint Náfrádi, Krisztina Nagy

The radical cation salt, ET2MnCuN(CN)(2), [ET=bis(ethylenedithio)tetrathiafulvalene] with an unusual three-dimensional anionic polymeric network is studied by x-ray diffraction, static susceptibility measurements, and electron spin resonance (ESR) at ...

Subcoercive cyclic electrical loading of lead zirconate titanate ceramics I: nonlinearities and losses in the converse piezoelectric effect

Dragan Damjanovic

The converse piezoelectric response of Pb(ZrxTi1−x)O3 ceramics is investigated as a function of material composition. The effects of the crystallographic phase and different dopants on piezoelectric nonlinearity are separately examined. For a linear depend ...

Giant Spin-Polarization and Magnetic Anisotropy of Nanostructures at Surfaces

Harald Brune

We present spin-polarized scanning tunneling microscopy Measurements demonstrating spin-polarizations of tip to 80 % for Co islands on a Pt(111) surface and a tunnel magneto resistance of 850 similar to% between the islands and an anti-ferromagnetic Cr-co ...

Magnetic-Field-Induced Soft-Mode Quantum Phase Transition in the High-Temperature Superconductor La1.855Sr0.145CuO4: An Inelastic Neutron-Scattering Study

Henrik Moodysson Rønnow, Joël Mesot, Johan Juul Chang

Inelastic neutron-scattering experiments on the high-temperature superconductor La1.855Sr0.145CuO4 reveal a magnetic excitation gap Delta that decreases continuously upon application of a magnetic field perpendicular to the CuO2 planes. The gap vanishes at ...

Localization, confinement, and field-controlled propagation of spin waves in

Dirk Grundler

Spin-wave modes in Ni80Fe20 thin-film antidot lattices are investigated using micromagnetic simulations and a semianalytical theoretical approach. The simulations reveal a rich eigenmode spectrum consisting of edge and center modes. We find both spatially ...

Evaluation of two commercial finite element packages for calculating AC losses in 2-D high temperature superconducting strips

Francesco Grilli, Frédéric Sirois, François Roy, Bertrand Dutoit

This paper compares the speed and accuracy of two commercial packages based on the finite element method (FEM) for calculating the AC losses in high temperature superconductors (HTS). The softwares investigated in this paper were COMSOL Multiphysics and FL ...
