We investigate a corona coupled with underlying disk through magnetic field and radiation field, and present emergent spectra. Due to buoyancy the magnetic flux loop emerges from the disk and reconnects with other loops in the corona, thereby releasing the magnetic energy to heat the coronal plasma. The energy is then radiated away through Compton scattering. By studying the energy balance in t...

Thin beams made of magnetorheological elastomers embedded with hard-magnetic particles (hard-MREs) are capable large deflections under an applied magnetic field. We propose a comprehensive framework, comprising beam model and 3D finite element modeling (FEM), to describe the behavior hard-MRE both uniform constant gradient fields. First, based on Helmholtz free energy bulk (3D) hard-MREs, we pe...

in daily-life applications and are key components of numerous electronic, data and medical devices as well as of many applications in the automotive sector. The combination of properties of the R sublattice (4f) and the T sublattice (3d) led to the dramatic improvement in the energy density (BH)max of hard magnetic materials during the last two decades. In the case of nanocrystalline R-T compou...

lag is a general term applied to coarse grained (> 2 mm), hard, but partially weathered rockfragments, which are concentrated at the surface through attrition of finer materials. based on morphology,mineralogy and the origin of lag from the cobar region of australia, lag may be conveniently grouped intothree broad morpho-mineralogical categories; (a) those with a rough, blocky, lithic morpholog...

The shape of TESLA accelerating structure can be improved to decrease maximal surface magnetic field by sacrificing and increasing maximal surface electric field. This sacrifice may be necessary because the magnetic field is a hard limit but electric field emission can be decreased by processing. For the case of superconducting cavities RF magnetic strength should be of a more concern.

Out-of-plane polyimide (PI) electromagnetic microactuators with different geometries are designed, fabricated and tested. Fabrication of the electromagnetic microactuators consists of 10 lm thick Ni/Fe (80/20) permalloy deposition on PI diaphragm by electroplating process, electroplating of copper planar coil with 10 lm thick, bulk micromachining, and excimer laser selective ablation. They are ...

Pulse-thermal processing (PTP) based on high-density plasma arc lamp technology has been utilized to crystallize melt-spun NdFeB-based amorphous ribbons to form magnetic nanocomposites consisting of Nd 2 Fe 14 B and α-Fe phases. After applying suitable pulses, the NdFeB-based ribbons were developed with hard magnetic properties. The highest coercivity can be obtained for ribbons with a thicknes...

Magnetic layers and layered structures with defined physical properties are of high interest for magnetoelectronic and magnetoelectromechanical applications as well as for magnetic data storage. New deposition technologies become more important in industrial branches for magnetic applications. Electrochemical deposition methods are favoured due to their low costs compared to physical deposition...
