Reaching the magnetic anisotropy limit of a 3d metal atom

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Luca Gragnaniello

Designing systems with large magnetic anisotropy is critical to realize nanoscopic magnets. Thus far, the magnetic anisotropy energy per atom in single-molecule magnets and ferromagnetic films remains typically one to two orders of magnitude below the theo ...

Empirical Monod-Beuneu relation of spin relaxation revisited for elemental metals

László Forró

Monod andBeuneu [P. Monod and F. Beuneu, Phys. Rev. B 19, 911 (1979)] established the validity of the ElliottYafet theory for elemental metals through correlating the experimental electron spin resonance linewidth with the so-called spin-orbit admixture co ...

Determination of sample temperature in unstable static fields by combining solid-state Br-79 and C-13 NMR

Geoffrey Bodenhausen

Monitoring the isotropic chemical shifts to calibrate the sample temperature presupposes a perfect stability of the static magnetic field. It can be difficult to satisfy this requirement in solid-state NMR measurements. This paper describes a simple way to ...

Unraveling the Core-Shell Structure of Ligand-Capped Sn/SnOx Nanoparticles by Surface-Enhanced Nuclear Magnetic Resonance, Mossbauer, and X-ray Absorption Spectroscopies

David Lyndon Emsley, Aaron James Rossini

A particularly difficult challenge in the chemistry of nanomaterials is the detailed structural and chemical analysis of multicomponent nano-objects. This is especially true for the determination of spatially resolved information. In this study, we demonst ...

A Low-Power PPM Demodulator for Remotely Powered Batteryless Implantable Devices

Catherine Dehollain, Enver Gürhan Kilinç, Franco Maloberti

A low-power PPM demodulator has been developed for remotely powered batteryless implantable devices. The required power is harvested by the magnetic coupling with external powering coils placed under the living space of the animal. The remote powering is t ...

Dynamic aggregation of the mid-sized gadolinium complex {Ph-4[Gd(DTTA)(H2O)(2)](-)(3)}

Lothar Helm, Pascal Miéville, Hugues Jaccard

A compound binding three Gd3+ ions, {Ph-4Gd(DTTA)(H2O)(2) (3)} (where H(5)DTTA is diethylenetriaminetetraacetic acid), has been synthesized around a hydrophobic center made up of four phenyl rings. In aqueous solution the molecules start to self-aggre ...

Coherent Excitonic Coupling in an Asymmetric Double InGaAs Quantum Well Arises from Many-Body Effects

Gaël Nardin, Rohan Singh, François Morier-Genoud

We study an asymmetric double InGaAs quantum well using optical two-dimensional coherent spectroscopy. The collection of zero-quantum, one-quantum, and two-quantum two-dimensional spectra provides a unique and comprehensive picture of the double well coher ...

An improved trap design for decoupling multinuclear RF coils

Rolf Gruetter, Eulalia Serés Roig

Purpose Multinuclear magnetic resonance spectroscopy and imaging require a radiofrequency probe capable of transmitting and receiving at the proton and non-proton frequencies. To minimize coupling between probe elements tuned to different frequencies, LC ( ...

Femtosecond Dynamics of Momentum-Dependent Magnetic Excitations from Resonant Inelastic X-Ray Scattering in CaCu2O3

Thorsten Schmitt

Taking spinon excitations in the quantum antiferromagnet CaCu2O3 as an example, we demonstrate that femtosecond dynamics of magnetic electronic excitations can be probed by direct resonant inelastic x-ray scattering (RIXS). To this end, we isolate the cont ...

Drug Screening Boosted by Hyperpolarized Long-Lived States in NMR

Geoffrey Bodenhausen, Sandrine Gerber, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud, Solène Marcelle Françoise Marie Passemard, Nicola Salvi, Daniele Mammoli, Roberto Buratto, Maninder Singh, Aurélien Laguerre

Transverse and longitudinal relaxation times (T11 and T1) have been widely exploited in NMR to probe the binding of ligands and putative drugs to target proteins. We have shown recently that long-lived states (LLS) can be more sensitive to ligand binding. ...
