Novel weak alignment techniques for nuclear magnetic resonance spectroscopy and applications to biomolecular structure determination [PDF]

, 2004
Nuclear magnetic resonance spectroscopy has continuously been developing ever since its introduction as a structural method in bioscience. Recently established residual dipolar coupling techniques yield information on long-range order in weakly ...

Charged particles and quasiperiodic oscillations around magnetized Schwarzschild black holes

European Physical Journal C: Particles and Fields, 2023
We study the motion of charged particles around Schwarzschild black holes immersed in external (i) asymptotically uniform, (ii) dipolar, and (iii) parabolic-like magnetic fields.

Increasing output power of electromagnetic vibration energy harvesters using improved Halbach arrays [PDF]

, 2013
This paper extends previously published studies into the performance of Halbach arrays for electromagnetic vibration energy harvesting. A Halbach array is a specific arrangement of permanent magnets that concentrates the magnetic field on one side of the

Do non-dipolar magnetic fields contribute to spin-down torques? [PDF]

, 2019
This is the final version. Available from the American Astronomical Society via the DOI in this recordMain sequence low-mass stars are known to spin-down as a consequence of their magnetised stellar winds.

Optimal backward light scattering by dipolar particles

Physical Review Research, 2020
The near-zero forward intensity condition for light scattering by a dielectric dipolar sphere is usually associated with the generalized second Kerker condition, at which equal amplitude electric and magnetic dipolar responses are phase-shifted by π.

Tuning Easy Magnetization Direction and Magnetostatic Interactions in High Aspect Ratio Nanowires

Nanomaterials, 2021
Cobalt nanowires have been synthesized by electrochemical deposition using track-etched anodized aluminum oxide (AAO) templates. Nanowires with varying spacing-to-diameter ratios were prepared, and their magnetic properties were investigated. It is found

A quantum spin-probe molecular microscope

Nature Communications, 2016
Single spin defects can allow high-resolution sensing of molecules under an applied magnetic field. Here, the authors propose a protocol for three-dimensional magnetic resonance imaging with angstrom-level resolution exploiting the dipolar field of a ...

Effect of the northward turning of the interplanetary magnetic field on the dipolarization [PDF]

Journal of Geophysical Research: Space Physics, 2013
An outstanding question in magnetospheric physics is whether the association between the northward turning of the interplanetary magnetic field (IMF) and the substorm onset is a random relation or a causal relation. In this work, we investigate the effect of the northward turning of the IMF on the dipolarization in the magnetotail by using the global ...
