Label-Free Hyper Rayleigh and Second Harmonic Scattering with High Efficiency

Sylvie Roke, Nikolaos Gomopoulos, Qinchao Sun

We present a method to perform hyper Rayleigh scattering from aqueous solutions and second harmonic scattering measurements from unlabeled interfaces of liposomes and nanoparticles in dilute solutions. The water and interfacial response can be measured on ...

Magnonic crystal wave guide with large spin-wave propagation velocity in CoFeB

Dirk Grundler

Propagating spin-wave spectroscopy is reported for two-dimensional CoFeB antidot lattices (ADLs) with perpendicular-to-plane magnetization. The magnonic crystals consist of square lattices of 190 nm diameter holes with different periods p. At p = 600 nm, t ...

Graphene Sublattice Symmetry and Isospin Determined by Circular Dichroism in Angle-Resolved Photoemission Spectroscopy

Klaus Kern, Isabella Gierz

The Dirac-like electronic structure of graphene originates from the equivalence of the two basis atoms in the honeycomb lattice. We show that the characteristic parameters of the initial state wave function (sublattice symmetry and isospin) can be determin ...

X-Treme beamline at SLS: X-ray magnetic circular and linear dichroism at high field and low temperature

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser, Thomas Schmidt

X-Treme is a soft X-ray beamline recently built in the Swiss Light Source at the Paul Scherrer Institut in collaboration with Ecole Polytechnique Federale de Lausanne. The beamline is dedicated to polarization-dependent X-ray absorption spectroscopy at hig ...

BaVS3 probed by V L edge x-ray absorption spectroscopy

László Forró, Helmuth Berger, Ana Akrap

Polarization dependent vanadium L edge x-ray absorption spectra of BaVS3 single crystals are measured in the four phases of the compound. The difference between signals with the polarizations E perpendicular to c and E parallel to c ( linear dichroism) cha ...

Optical properties of mesogen-coated gold nanoparticles

Toralf Scharf

In this work, the physical and optical properties of gold nanoparticles functionalized with laterally grafted nematic ligands were studied. In particular, the influence of the nanoparticle size on the mesomorphic behavior and optical properties of the comp ...

An Endohedral Single-Molecule Magnet with Long Relaxation Times: DySc_{2}N@C_{80}

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

The magnetism of DySc2N@C80 endofullerene was studied with X-ray magnetic circular dichroism (XMCD) and a magnetometer with a superconducting quantum interference device (SQUID) down to temperatures of 2 K and in fields up to 7 T. XMCD shows hysteresis of ...

Global gyrokinetic ITG turbulence simulations of ITER

Laurent Villard, Stephan Brunner, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Paolo Angelino, Thibaut Vernay

Global gyrokinetic simulations of ion temperature gradient (ITG) driven turbulence in an ideal MHD ITER equilibrium plasma are performed with the ORB5 code. The noise control and field-aligned Fourier filtering procedures implemented in ORB5 are essential ...

Anisotropic spin gaps in BiAg2-Ag/Si(111)

Klaus Kern, Marco Grioni, Alberto Crepaldi, Emmanouil Frantzeskakis

We present a detailed analysis of the band structure of the root 3 x root 3 R 30 degrees BiAg2/Ag/Si(111) trilayer system by means of high resolution Angle Resolved Photoemission Spectroscopy (ARPES). BiAg2/Ag/Si(111) exhibits a complex spin-polarized elec ...
