Energy transfer by magnetic dipole—magnetic dipole interaction

Chemical Physics Letters, 1993
Abstract The magnetic dipole interaction mechanism is shown to be important in a nonradiative energy transfer process of a lanthanide ion in a centrosymmetric environment. The concentration quenching of near-ultraviolet luminescence in Cs 2 NaTmCl 6 may be explained by this mechanism, the calculated nonradiative transfer rate from the donor Tm 3 ...

On magnetic dipole–dipole interactions of nanoparticles in magnetic particle imaging [PDF]

Physics in Medicine & Biology, 2017
Magnetic dipole-dipole (MDD) interactions between iron oxide nanoparticles can influence the sensitivity, image resolution and quantification of magnetic particle imaging (MPI). For the first time, the Landau-Lifshitz-Gilbert equation (LLG) for MDD interactions has been solved to investigate the effect of MDD interactions on the MPI spectrum.

The radiofrequency magnetic dipole discharge

Physics of Plasmas, 2016
This paper describes a novel and simple concept of plasma source, which is able to produce a radiofrequency magnetized discharge with minimal power requirements. The source is based on the magnetron concept and uses a permanent magnet as an active electrode. The dipolar field produced by the magnet confines the electrons, which cause further ionization,

A Real-Time Magnetic Dipole Localization Method Based on Cube Magnetometer Array

IEEE transactions on magnetics, 2019
Magnetic dipole localization methods have a wide application range. Resolving equations of magnetic gradient tensor is a classical method to obtain the direction of the relative position vector, but the real solution hides in four possible solutions. The

Planar Self-Balanced Magnetic Dipole Antenna With Wide Beamwidth Characteristic

IEEE Transactions on Antennas and Propagation, 2019
A design approach to a novel planar self-balanced magnetic dipole antenna with wide beamwidth is proposed. By incorporating a parasitic rectangular strip to a circular sector magnetic dipole at its angular bisector on the bottom layer, a virtual magnetic

Magnetic field of a dipole and the dipole–dipole interaction

European Journal of Physics, 2007
With a data-acquisition system and sensors commercially available, it is easy to determine magnetic fields produced by permanent magnets and to study the dipole–dipole interaction for different separations and angular positions of the magnets. For sufficiently large distances, the results confirm the 1/R3 law for the magnetic field and the 1/R4 law for

Magnetic dipole imaging by a scanning magnetic microscope

Measurement Science and Technology, 2007
A reconstruction technique to evaluate residual magnetic fields and simulate magnetic images due to dipole distribution in ferromagnetic samples has been proposed in connection with a scanning magnetic microscope based on a high-Tc superconducting quantum interference device (SQUID).

Engineering electric and magnetic dipole coupling in arrays of dielectric nanoparticles

, 2018
Dielectric nanoparticles with both strong electric and magnetic dipole (ED and MD) resonances offer unique opportunities for efficient manipulation of light-matter interactions. Here, based on numerical simulations, we show far-field diffractive coupling
