IEEE Access, 2017 The radiation behavior of the fractional-order, resonant mode within a circular sector cavity radiator is revealed at first, and then, it is employed to design a novel, planar quasi-isotropic magnetic dipole antenna.

Magnetic dipole interactions in crystals
Physical Review B, 2016 The influence of magnetic dipole interactions (MDIs) on the magnetic properties of local-moment spin systems is investigated. The eigenvalues and eigenvectors of the MDI tensor are determined for a wide variety of spin lattices and magnetic wavevectors in the magnetically ordered state with collinear moment alignments.

Magnetic Field Modification of Optical Magnetic Dipoles
Nano Letters, 2015 Acting on optical magnetic dipoles opens novel routes to govern light-matter interaction. We demonstrate magnetic field modification of the magnetic dipolar moment characteristic of resonant nanoholes in thin magnetoplasmonic films. This is experimentally shown through the demonstration of the magneto-optical analogue of Babinet's principle, where ...

The Submm and mm Excess of the SMC: Magnetic Dipole Emission from Magnetic Nanoparticles?
, 2012 The Small Magellanic Cloud (SMC) has surprisingly strong submm and mm-wavelength emission that is inconsistent with standard dust models, including those with emission from spinning dust.

On the magnetic dipole energy expression of an arbitrary current distribution [PDF]
arXiv, 2012 We show that the magnetic dipole energy term appearing in the expansion of the magnetic potential energy of a localized current distribution has the form $ U= + \bf{m} \cdot \bf{B}$ which is wrong by a sign from the well known $ - \bf{m} \cdot \bf{B}$ expression.

Spin-orbit torque induced dipole skyrmion motion at room temperature
, 2018 We demonstrate deterministic control of dipole-field-stabilized skyrmions by means of spin-orbit torques arising from heavy transition-metal seed layers.

Interaction between an electric charge and a magnetic dipole of any kind (permanent, para- or dia- magnetic or superconducting) [PDF]
arXiv, 2015 The interaction between point charge and magnetic dipole is usually considered only for the case of a rigid ferromagnetic dipole (constant-current): here the analysis of force, momentum and energy (including the energy provided by the internal current generator) is generalised to any magnetic dipole behaviour: rigid, paramagnetic, diamagnetic or ...
arxiv
, 2005 We show that for asymptotically vanishing Maxwell fields in Minkowski space with non-vanishing total charge, one can find a unique geometric structure, a null direction field, at null infinity.

Determination of the Δ++ magnetic dipole moment
Physics Letters B, 2001 We study the elastic and radiative pi+ p scattering within a full dynamical model which incorporates the finite width effects of the Delta++. The scattering amplitudes are invariant under contact transformations of the spin 3/2 field and gauge-invariance is fulfilled for the radiative case.

Bound states of a fermion-dyon system
European Physical Journal C: Particles and FieldsThe bound states of fermions in the external field of an Abelian dyon are studied here both analytically and numerically. Their existence is due to the dyon’s electric charge resulting from a polarization of the fermionic vacuum. The configuration of the
