Magnetic manipulation of objects within the body is a growing field of research since the second half of the last century. Therapeutic and diagnostic capabilities offered by such technology are extended with the clinical need to make procedures less invasi ...
An analytical formula for the shape derivative of the magnetic field integral equation (MFIE) method of moments (MoM) system matrix (or impedance matrix) is derived and validated against finite difference formulas. The motivation for computing the shape de ...

Permanent magnet axial flux motors are very well adapted to applications requiring a very short active length and a big diameter. They also have been used for micro-motors. Because of their size, these motors require the use of a permanent magnet and their ...
In this article, we investigate the equations of magnetostatics for a configuration where a ferromagnetic material occupies a bounded domain and is surrounded by vacuum. Furthermore, the ferromagnetic law takes the form ...
All-electrical spin-wave spectroscopy and frequency-resolved magneto-optical Kerr-effect measurements are combined to study spin waves propagating through a magnetic antidot lattice nanopatterned from a Ni80Fe20 thin film. Spin waves are injected from a pl ...
A half-century quest for improving resolution in Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) has enabled the study of molecular structures, biological interactions, and fine details of anatomy. This progress largely relied on the ...
Phonon frequency and linewidth as well as quasielastic scattering due to spin energy fluctuations are used to evaluate the evolution of spin correlations in a spin chain system with considerable interchain coupling. In the compound CuSe2O5 these interactio ...
A relationship between the dipolar and the chemical-shift scaling factors of cyclic radio-frequency irradiation schemes is introduced. This scaling factor theorem is derived analytically using Average Hamiltonian Theory, and its validity is illustrated num ...
We extend the mimetic finite difference (MFD) method to the numerical treatment of magnetostatic fields problems in mixed div-curl form for the divergence-free magnetic vector potential. To accomplish this task, we introduce three sets of degrees of freedo ...
In a magnetic nanowire, a magnetic domain wall (DW) can move along the wire when an applied magnetic field or a spin-polarized current is applied. A magnetic spin-valve device composed of two nanowires connected by a nanosized constriction was prepared, on ...
