The Role of Magnetic Dipole—Dipole Coupling in Quantum Single-Molecule Toroics

open access: yesMagnetochemistry, 2022
For single-molecule toroics (SMTs) based on noncollinear Ising spins, intramolecular magnetic dipole–dipole coupling favours a head-to-tail vortex arrangement of the semi-classical magnetic moments associated with a toroidal ground state.

[2.2]Paracyclophane-Based Chiral Platforms for Circularly Polarized Luminescence Fluorophores and Their Chiroptical Properties: Past and Future

open access: yesFrontiers in Chemistry, 2020
Quality of CPL fluorophore is defined by the vectors of electric dipole transition moment and imaginary magnetic dipole transition moment. The aim of this review is to introduce readers to a chiral moiety applicable to CPL studies focusing on chiral ...

Full Tensor Eigenvector Analysis on Air-Borne Magnetic Gradiometer Data for the Detection of Dipole-Like Magnetic Sources

open access: yesSensors, 2017
The detection of dipole-like sources, such as unexploded ordnances (UXO) and other metallic objects, based on a magnetic gradiometer system, has been increasingly applied in recent years.

Evolution of the plasma sheet electron pitch angle distribution by whistler-mode chorus waves in non-dipole magnetic fields [PDF]

open access: yesAnnales Geophysicae, 2012
We present a detailed numerical study on the effects of a non-dipole magnetic field on the Earth's plasma sheet electron distribution and its implication for diffuse auroral precipitation.

Magnetic dipoles and electric currents [PDF]

open access: yesAmerican Journal of Physics, 2009
We discuss several similarities and differences between the concepts of electric and magnetic dipoles. We then consider the relationship between the magnetic dipole and a current loop and show that in the limit of a pointlike circuit, their magnetic fields coincide.

Ray-tracing simulations of whistler-mode wave propagation in different rescaled dipole magnetic fields

open access: yesEarth and Planetary Physics, 2022
Kinetic simulation is a powerful tool to study the excitation and propagation of whistler-mode waves in the Earth’s inner magnetosphere. This method typically applies a scaled-down dipole magnetic field to save computational time.

Writing skyrmions with a magnetic dipole [PDF]

open access: yesJournal of Applied Physics, 2018
We demonstrate numerically, through energy minimization on large spin lattices, that one can write skyrmions in a thin magnetic film with a magnetic dipole of a few tens of nanometer in size. Nucleation of non-chiral skyrmions as well as chiral skyrmions formed by the Dzyaloshinskii-Moriya interaction has been investigated.

Magnetization Effects in Superconducting Dipole Magnets [PDF]

open access: yesIEEE Transactions on Nuclear Science, 1977
Magnetization effect of superconductor on the field quality has been investigated for some of the typical Energy Doubler bending magnets. Calculations were made using the computor program GFUN2D and compared with some measured results. Agreement between them is good.
