Dielectric materials play an important role in broad applications, such as electrical and electromagnetic applications. This research studied the prediction of effective permeability of composite and nanocomposite dielectric materials based on theoretical analysis to specify the effects of embedded magnetic inclusions in enhancing magnetic properties of dielectrics. Effective permeability of Pl...

In this work, nanocrystalline Fe85Si10Ni5 soft magnetic powders were prepared by mechanical alloying and subsequent annealing to reduce the internal stresses and lattice strains. The powders were mixed with phenolic resin and warm pressed to produce nanostructured soft magnetic composites. The effect of annealing time and temperature on the crystalline structure, microstructure and magnetic pro...

We prepared an Fe-based ribbon with controlled permeability and low magnetic loss by Continuous Stress-Annealing by Joule Heating (CSA-JH) method. The shortest annealing time necessary for the obtaining of the ribbons with completely developed anisotropy was 1 sec, but in order to obtain the sufficiently crystallized ribbons with small saturation magnetostriction it is required to perform annea...

In the present work, we investigate the tunability of the magnetic response of a new structure. A lattice of periodically arranged close-packed square conducting rings has been studied for this purpose. Here, instead of enhancing the magnetic activity via resonance, like in split-ring resonators, we concentrate on the analysis of the interactions between these rings. The core idea is to design ...

effects of hall current, ion-slip and coriolis force on unsteady mhd couette-hartmann flow of a viscous incompressible electrically conducting fluid through a porous medium bounded by porous plates in the presence of a uniform transverse magnetic field which is either fixed relative to the fluid or to the moving porous plate is investigated using laplace transform technique. the expressions for...

The magnetic permeabiility and the thickness of the socalled %on"magnetic grain boundary were studied for a MgMnZn-femte with composition M~,J~,&ln,lFe,,,03,m For the mono-domain situation the grain size dependence of the effective initial permeability is well described by the nonmagnetic grain boundary model. A gradual increase of permeability with grain size around the transition from monoto ...

This report evaluates a variety of dental materials with respect to MR imaging artifacts and their mechanisms of production. A 0.15-T superconducting system and an MR phantom were used in assessing imaging artifacts. Several in-vivo studies were also carried out. The dental materials were analyzed for composition and magnetic permeability and the results were compared with the artifacts produce...
