INTERMAG 2014 - IEEE International Magnetics Conference
Intermag is the premier conference on applied magnetics which allows scientists and engineers from all over to world to meet and discuss novel developments in magnetics, magnetic materials and associated technologies.
The Conference on Precision Electromagnetic Measurements (CPEM) is devoted to topics related to electromagnetic measurements at the highest accuracy levels. These cover the frequency spectrum from dc through the optical region. A major focus of this conference is quantum devices that relate electrical standards to fundamental constants and the international system of units.
2000 8th International Conference on Ferrites
Korolev, K.A.; Chen, S.; Afsar, M.N. Precision Electromagnetic Measurements Digest, 2008. CPEM 2008. Conference on, 2008
This paper presents transmittance spectra and complex magnetic permeability and dielectric permittivity parameters of pure and mixed powdered barium ferrites, nickel zinc manganese ferrites and nickel cobalt copper ferrites in a broad-band millimeter wave frequency range. A free space, millimeter wave magneto-optical approach has been successfully employed for precise characterization of ferrite materials. Frequency dependences of the magnetic permeability of ...

Co/Ti-substituted M-type BaFe12-2xCoxTixO19 ferrites were investigated for multilayer inductor applications. Single-phase ferrite powders were prepared at 1000°C through the mixed oxide route. After sintering at 1300°C a maximum permeability of μ' = 37 is observed for x = 1.2. The addition of a glass sintering aid shifts the temperature of maximum shrinkage down to below 900°C and dense samples were ...

This paper describes the progress that have been made in developing improved power ferrites for high frequency use. This development project has two specific goals (1) develop a ferrite which can be operated at elevated flux densities in the 1-10 MHz range with acceptable loss (2) develop ferrites for 1.0 MHz or lower frequencies use which can be operated at ...

The microwave power absorption characteristics of five ferrites, BaFe12O19, SrFe12O19, CuFe2O 4, CuZnFe4O4 and NiZnFe4O4, have been studied by determining the average power absorption patterns of the ferrite slabs using the derived power equations with consideration of both microwave dielectric and magnetic losses. It is shown that microwave power dissipates rapidly in the ferrites with a thickness of microwave penetration ...
Inui, T.; Ogasawara, N. Magnetics, IEEE Transactions on, 1977
This paper presents a review of polycrystalline microwave ferrites with specific reference made to the grain size. Fine-grained ferrites and large- grained ferrites as referred to in this article stand for the ferrites with an average grain size of 2 μm or less and those of 100 μm or larger, respectively. Fine-graining of ferrites is one of the state-of-the-arts techniques ...
