Using a computational procedure, the real and imaginary components of the circumferential permeability could be determined from the complex impedance data. We show that the temperature dependence of the permeability is useful to study magnetic phase transitions, whereas valuable information on domain-wall...
The effective magnetic permeability mu and effective dielectric constant epsilon are two equally important quantities for the characterization of electromagnetic properties of composites. For granular ferromagnetic metals, however, the presence of permanent magnetic moments means that the Maxwell-Garnett theory...
Substitution of expression for M makes B = μH, where μ = μ0(1 +χ) is the magnetic permeability of matter. The entire information about susceptibility of an object and how it is related to the B, or B0 as it is called in MR imaging, is lumped into μ through χ. Modulation of...

High permeability amorphous magnetic material To obtain a high permeability magnetic core, the core is made of a 5 to 25 &mgr;m thick ribbon of a Co-based amorphous alloy with a Curie temperature Tc between 120° C. and 270° C., and further heat treated at a temperature below... T ...
Soft magnetic materials with stable permeability up to hundreds of megahertz (MHz) are urgently needed for integrated transformers and inductors, which are crucial in the more-than-Moore era. However, traditional frequency-stable soft magnetic ferrites suffer from low saturation magnetization and temperat...
