Energy transfer by magnetic dipole—magnetic dipole interaction
Chemical Physics Letters, 1993Abstract 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
Physics in Medicine & Biology, 2017Magnetic 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.

In the previous chapter we assumed that particle sizes are much smaller than the radiation wavelength. This gave us the possibilities of considering the field within the limits of the particle as being independent of the coordinates and analyzing the influence of a single electric field on a substance.

Magnetization of Magnetite Nanoparticles Mediums with Weak Magnetic Dipole–Dipole Interaction
Journal of Nanoscience and Nanotechnology, 2011Magnetization expression of weak interacting (mH/kT = 1-1.5) magnetite nanoparticles mediums was determined. Experimental and calculated magnetization curves, initial magnetic susceptibility of magnetite nanoparticle mediums were compared. It is showed are agree.

Laser-Induced Magnetic Dipole Spectroscopy
The Journal of Physical Chemistry Letters, 2016Pulse electron paramagnetic resonance measurements of nanometer scale distance distributions have proven highly effective in structural studies. They exploit the magnetic dipole-dipole coupling between spin labels site-specifically attached to macromolecules.

Magnetic dipole imaging by a scanning magnetic microscope
Measurement Science and Technology, 2007A 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).

Dipole‐Dipole Interaction in Fine Particle Magnets
physica status solidi (b), 1990Contrairement a l'approche precedente qui consistait a caracteriser chaque particule par sa coercitivite propre on considere ici des amas inclus dans un environnement. Les spheres de plus proche voisinage sont decrites comme des particules discretes alors que les autres sont considerees par leur champ de ...

A recent book rejects the amperian-current model of a magnetic dipole and accepts the magnetic-charge model, because the first model would lead to inconsistencies in the interpretation of Poynting's theorem. It is shown that the inconsistencies are only apparent.

GEOPHYSICS, 1959
Two nomograms or alignment charts are presented for the solution of the magnetic‐dipole equations for magnetic intensity over a dipping dipole. The two charts are used in conjunction with each other and are as accurate as is needed for field work. One of these charts will be found useful also in other calculations involving [Formula: see text].
