Molecular and Spin Dynamics in the Paramagnetic Endohedral Fullerene Gd3N@C-80

László Forró, Bálint Náfrádi, Agnes Antal

Gd3N@C-80 endohedral fullerene, a starting material for a potential magnetic resonance imaging contrast agent, is investigated by high-frequency electron spin resonance (ESR) and SQUID magnetometry. The magnetic moments of the three Gd ions of the endohedr ...

Improving Sensitivity in Solid State NMR : Surfaces, Quadrupolar Nuclei and Dynamic Nuclear Polarization

Sensitivity in Nuclear Magnetic Resonance (NMR), especially in solid-state NMR, has always been a challenging and important issue and thus a motivation for new developments. The magnetic field B0, the gyromagnetic ratios of the observed nuclei, as well as ...

Strong coupling of Sm and Fe magnetism in SmFeAsO as revealed by magnetic x-ray scattering

Henrik Moodysson Rønnow, Xiao Wang

The magnetic structures adopted by the Fe and Sm sublattices in SmFeAsO have been investigated using element-specific x-ray resonant and nonresonant magnetic scattering techniques. Between 110 and 5 K, the Sm and Fe moments are aligned along the c and a di ...

Structural Composition of First-Neighbor Shells in GeSe2 and GeSe4 Glasses from a First-Principles Analysis of NMR Chemical Shifts

Alfredo Pasquarello, Carlo Massobrio, Mikhail Kibalchenko

Isotropic chemical shifts and quadrupole coupling parameters of Se-77 and Ge-73 nuclei in GeSe2 and GeSe4 glasses are determined through density-functional NMR calculations on amorphous model structures generated by ab initio molecular dynamics. The compar ...

Magnetocrystalline anisotropy energy of Co and Fe adatoms on the (111) surfaces of Pd and Rh

Harald Brune, Stefano Rusponi, Pietro Gambardella, Anne Lehnert, Markus Etzkorn, Géraud Moulas

We performed a combined theoretical and experimental investigation of the orbital magnetism and magnetocrystalline anisotropy of isolated Co and Fe adatoms on Pd(111) and Rh(111). Theoretical calculations of the spin and orbital moments are based on ab ini ...

Hyperpolarizing Gases via Dynamic Nuclear Polarization and Sublimation

Rolf Gruetter, Geoffrey Bodenhausen, Jean-Philippe Ansermet, Pascal Miéville, Arnaud Comment, Jean-Noël Hyacinthe, Sami Jannin, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja, François Lazeyras

A high throughput method was designed to produce hyperpolarized gases by combining lowtemperature dynamic nuclear polarization with a sublimation procedure. It is illustrated by applications to 129Xe nuclear magnetic resonance in xenon gas, leading to a si ...

Phosphinic derivative of DTPA conjugated to a G5 PAMAM dendrimer: an 17O and 1H relaxation study of its Gd(III) complex

André Merbach, Lothar Helm, Eva Jakab Toth, Petra Lebduskova

A DTPA-based chelate containing one phosphinate group was conjugated to a generation 5 polyamidoamine (PAMAM) dendrimer via a benzylthiourea linkage. The Gd(III) complex of this novel conjugate has potential as a contrast agent for magnetic resonance imagi ...

A drift-kinetic Semi-Lagrangian 4D code for ion turbulence simulation

Olivier Sauter, Laurent Villard

A new code is presented here, named Gyrokinetic SEmi-LAgragian (GYSELA) code, which solves 4D drift-kinetic equations for ion temperature gradient driven turbulence in a cylinder (r, theta, z). The code validation is performed with the slab ITG mode that o ...
