Plasmaspheric dynamics resulting from the hallowe'en 2003 geomagnetic storms [PDF]

open access: yes, 2009
Cross-phase-derived plasma mass density trends during the Hallowe'en 2003 geomagnetic storms are presented for 38° magnetic latitude 63° (1.61 ≤ L ≤ 5.10), using data from the SAMNET (Subauroral Magnetometer Network), BGS (British Geological Survey), and

Nonlinear shear Alfvén resonances in a dipolar magnetic field [PDF]

open access: yes, 1997
The effect of the ponderomotive force (PF) on the temporal evolution of shear Alfven field line resonances (FLRs) is considered for a magnetic dipole geometry appropriate to the Earth's magnetosphere. We derive a set of equations which describes the

Spin distillation cooling of ultracold Bose gases

open access: yesScientific Reports, 2021
We study the spin distillation of spinor gases of bosonic atoms and find two different mechanisms in $${}^{52}$$ 52 Cr and $$^{23}$$ 23 Na atoms, both of which can cool effectively.

Stellar magnetic field database and extrapolation method

open access: yesAstronomy & Astrophysics
Context. During the past two decades, thousands of stellar magnetic fields have been measured using the Zeeman-Doppler imaging method. No unified database gathers all measurements in a homogeneous way. Aims.

Intrinsic chiral field as vector potential of the magnetic current in the zig-zag lattice of magnetic dipoles

open access: yesScientific Reports, 2023
Chiral magnetic insulators manifest novel phases of matter where the sense of rotation of the magnetization is associated with exotic transport phenomena.

The fitting of a dipolar magnetic field by a dipole model

open access: yesEarth and Planetary Physics
Many planets, including the Earth, possess a global dipolar magnetic field. To diagnose the interior source of the dipolar field, researchers usually adopt a dipole model consisting of six parameters to fit the observed dataset of the magnetic field ...

A quantum spin-probe molecular microscope

open access: yesNature 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 ...

Optimal backward light scattering by dipolar particles

open access: yesPhysical 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

open access: yesNanomaterials, 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
