Magnetic and dielectric order in the kagomelike francisite Cu3Bi(SeO3)(2)O2Cl

Helmuth Berger

We report a single-crystal neutron diffraction and inelastic neutron scattering study on the spin 1/2 cuprate Cu3Bi(SeO3)(2)O2Cl, complemented by dielectric and electric polarization measurements. The study clarifies a number of open issues concerning this ...

Magnetic properties of surface-adsorbed single rare earth atoms, molecules, and atomic scale clusters

Aparajita Singha

This thesis presents combined experimental and theoretical investigations of nanoscale, surface-supported magnets based on rare earths (RE) to understand and control the magnetic properties down to the scale of single atoms. We present the effects of adato ...

Magnetic properties of AMoOPO4Cl (A=K,Rb) with Mo5+ ions in the 4d1 electronic configuration are investigated by magnetization, heat capacity, and nuclear magnetic resonance (NMR) measurements on single crystals, combined with powder neutron diffraction ex ...

Hyperpolarization by dynamic nuclear polarization relies on the microwave irradiation of paramagnetic radicals dispersed in molecular glasses to enhance the nuclear magnetic resonance (NMR) signals of target molecules. However, magnetic or chemical interac ...

Measuring Nano- to Microstructures from Relayed Dynamic Nuclear Polarization NMR

David Lyndon Emsley, Aaron James Rossini, Moreno Lelli, Arthur César Pinon, Pierrick Berruyer, Etienne Christophe Socie, Judith Schlagnitweit

We show how dynamic nuclear polarization (DNP) NMR can be used in combination with models for polarization dynamics to determine the domain sizes in complex materials. By selectively doping a source component with radicals and leaving the target undoped, w ...

Dynamic Nuclear Polarization Surface Enhanced NMR Spectroscopy (DNP SENS) is an emerging technique that allows access to high-sensitivity NMR spectra from surfaces. However, DNP SENS usually requires the use of radicals as an exogenous source of polarizati ...

Magnetic structure and magnon dynamics of the quasi-two-dimensional antiferromagnet FePS3

Henrik Moodysson Rønnow, Diane Virginie Marie Lançon

Neutron scattering from single crystals has been used to determine the magnetic structure and magnon dynamics of FePS3, an S = 2 Ising-like quasi-two-dimensional antiferromagnet with a honeycomb lattice. The magnetic structure has been confirmed to have a ...

Microwave-gated dynamic nuclear polarization

David Lyndon Emsley, Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Arthur César Pinon, Xiao Ji, Mathieu Baudin

Dissolution dynamic nuclear polarization (D-DNP) has become a method of choice to enhance signals in nuclear magnetic resonance (NMR). Recently, we have proposed to combine cross-polarization (CP) with D-DNP to provide high polarization P(C-13) in short bu ...

Royal Society of Chemistry2016

Although free-living and obligate intracellular bacteria are both polarized it is unclear whether the underlying polarization mechanisms and effector proteins are conserved. Here we dissect at the cytological, functional and structural level a conserved po ...
