A practical guide to in vivo proton magnetic resonance spectroscopy at high magnetic fields
Localized proton magnetic resonance spectroscopy ((1)H-MRS) is a noninvasive tool for measuring in vivo neurochemical information in animal and human brains. With the increase of magnetic field strength, whereas localized (1)H-MRS benefits from higher sens ...
Elsevier2017Novel Instrumentation and Methods for Chemical Applications of Dissolution Dynamic Nuclear Polarization
One of the major disadvantages of Nuclear Magnetic Resonance (NMR) is its low sensitivity, mainly due to a very low spin polarization. Since 2003, Dissolution Dynamic Nuclear Polarization (D-DNP) provides a way of overcoming this drawback in solution by in ...
EPFL2016Optimizing dissolution dynamic nuclear polarization
This article is a short review of some of our recent developments in dissolution dynamic nuclear polarization (d-DNP). We present the basic principles of d-DNP, and motivate our choice to step away from conventional approaches. We then introduce a modified ...
Academic Press Inc Elsevier Science2016Methods to hyperpolarize nuclear spins via dissolution and sublimation DNP at high magnetic field
Dynamic Nuclear Polarization (DNP) is, nowadays, the most well-established and widespread Nuclear Magnetic Resonance (NMR) hyperpolarization technique. With respect to other methods, the main advantage of DNP is, with no doubt, its versatility. In theory e ...
EPFL2016Method for the generation of radicals for dynamic nuclear polarization and uses thereof for nmr, mrs and mri
Christophe Roussel, Arnaud Comment, Tim Rolf Eichhorn
A method for the preparation of a sample comprising highly polarized nuclear spins is proposed, comprising at least the following steps: a) provision of molecules with 1,2-dione structural units and/or molecules with 2,5-diene-1,4-dione structural units in ...
2016Compact Microwave Cavity with Increased Magnetic Field Homogeneity
Anja Skrivervik, Anton Evgeniev Ivanov
In this study we aim at improving the homogeneity of the magnetic field inside a microwave resonator cavity designed in line with the development of a novel, high performance frequency standard. We study the effect of modified boundary conditions applied t ...
2016Magnetic states and spin-wave modes in single ferromagnetic nanotubes
In this thesis the electrical properties, magnetic states and spin wave resonances of individual magnetically hollow ferromagnetic nanotubes have been studied. They were prepared from the different materials Nickel (Ni), Permalloy (Py) and Cobalt-Iron-Boro ...
EPFL2014Spin-Relaxation Anisotropy in a GaAs Quantum Dot
We report that the electron spin-relaxation time T1 in a GaAs quantum dot with a spin-1/2 ground state has a 180° periodicity in the orientation of the in-plane magnetic field. This periodicity has been predicted for circular dots as being due to the inter ...
2014Determination of sample temperature in unstable static fields by combining solid-state Br-79 and C-13 NMR
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 ...
Elsevier2014Dissipation processes in the insulating skyrmion compound Cu2OSeO3
Ivica Zivkovic, Helmuth Berger
We present a detailed study of the phase diagram surrounding the skyrmion lattice (SkL) phase of Cu2OSe2O3 using high-precision magnetic ac susceptibility measurements. An extensive investigation of transition dynamics around the SkL phase using the imagin ...
