For over 100 years, the group-theoretic characterization of crystalline solids has provided the foundational language for diverse problems in physics and chemistry. However, the group theory of crystals with commensurate magnetic order has remained incom
This is inferred to be one of the reasons why density sharply decreases from the chromosphere to the transition region and the corona. The different solar-cycle behaviors of different categories of magnetic elements imply that their origins may be different. At the solar shallow subsurface (the ...
Magnetic force densities are computed by differentiation of the magnetic energy density distribution obtained by finite-element analysis. The computed forces on small permeable particles are shown to agree reasonably well with a classical formula by Oberteuffer. The method is applied to both planar sep...
Interpolation formula for the energy of a two-dimensional electron gas in the lowest Landau level The energy per particle of a two-dimensional electron system in the lowest Landau level is studied making use of the particle-hole symmetry. An accurate in... G Fano,F Ortolani - 《Physical Revi...
Figure 3(Aa) draws the influences of a current on the magnetic flux density. The non-linear behavior is due to the magnetic core. The higher current I drawn from the power supply will end up creating more heat (power dissipation I2R where R is the resistance) on the electromagnet, ...
We reported on three-dimensional (3D) superparamagnetic scaffolds that enhanced the mineralization of magnetic nanoparticle-free osteoblast cells. The scaffolds were fabricated with submicronic resolution by laser direct writing via two photons polymeriz
The two-dimensional Fourier transform is given by: Φ(u, v)=∬ +∞ -∞ φ(x, y)e -i(ux+vy)dxdy and its inverse is given by φ(x, y)= 1 4π 2 ∬ +∞ -∞ Φ(u, v)e i(ux+vy)dudv Where u and v are spatial frequency numbers in the x- and y-directions ...
and both magnetic fields show a relationship with the magnetic flux density, , described by the formula: where μois the magnetic permeability of vacuum. For most materials, the induced magnetic polarization is parallel to , in this case the materials are called "isotropic." Thus, χ is a sc...
A bulk amorphous metal magnetic component has a plurality of layers of ferromagnetic amorphous metal strips laminated together to form a generally three-dimensional part having the shape of a polyhedron. The bulk amorphous metal magnetic component may in
