Search for nuclear magnetic resonance evidence of spin accumulation

Aurore Rudolf

Developments towards an understanding of the nature of conductance at the interface between two different metallic layers – ferromagnetic and non magnetic – as well as the discovery of giant magnetoresistance have stirred attention from both the scientific ...

High-Resolution NMR in Magnetic Fields with Unknown Spatiotemporal Variations

Geoffrey Bodenhausen

Nuclear magnetic resonance (NMR) experiments are usually carried out in homogeneous magnetic fields. In many cases, however, high-resolution spectra are virtually impossible to obtain because of the inherent heterogeneity of the samples or living organisms ...

2009

In solution-state NMR spectroscopy, dynamic processes can be probed provided the nuclear relaxation rate constant does not exceed the rate constant of the process. Phenomena occurring on a time scale longer than the spin-lattice relaxation time constant, T ...

EPFL2009

A transverse-dephasing optimized (SE)-E-3 (spin-state selective excitation) method is implemented in solid-state NMR experiments of uniformly labeled protein samples, and it is shown to provide a simultaneous significant gain in both resolution (up to a fa ...

Magnetic correlations at graphene edges: Basis for novel spintronics devices

Oleg Yazyev

Magnetic zigzag edges of graphene are considered as a basis for novel spintronics devices despite the fact that no true long-range magnetic order is possible in one dimension. We study the transverse and longitudinal fluctuations of magnetic moments at zig ...

Magnetohydrodynamic pumping in nuclear magnetic resonance environments

Nico de Rooij

We present a DC magnetohydrodynamic (MHD) pump as component of a nuclear magnetic resonance (NMR) microfluidic chip. This is the first time that MHD pumping in an NMR environment was observed and demonstrated. This chip generates a maximum flow rate of 1.5 ...

Microfabricated NMR-probes for the analysis of living cells

Microfabricated probes for Nuclear Magnetic Resonance (NMR) spectroscopy of living cells in very small quantities have been developed in this thesis. These microprobes are based on two different sample interfaces: Channel microprobes, which confine a stack ...

Fabrication and characterisation of ultrasensitive monocrystalline silicon cantilevers with integrated magnetic tips

Alain Dysli

During this project, ultrasensitive cantilevers designed for nuclear magnetic resonance applications were fabricated and characterised. The cantilevers are 500, 340 or 200 μm long, 10 or 20 μm wide and 500 or 340 nm thick and integrate a thin film of cobal ...

2006

Many physical properties of high-temperature superconductors are two-dimensional phenomena derived from their square-planar CuO2 building blocks. This is especially true of the magnetism from the copper ions. As mobile charge carriers enter the CuO2 layers ...

2005

We perform first-principles molecular dynamics of liquid oxygen in which the magnetic structure evolves according to a generalized density-functional scheme allowing for noncollinear spin configurations. We investigate both structural correlations between ...
