We compare the diagonal /spl mu/ and off-diagonal /spl kappa/ permeability tensor components of magnetized polycrystalline ferrites given by the theoretical model of Gelin and Berthou with experimental ones at microwave frequencies. We used a broad-b

The induced anisotropy of magnetized nanocomposite samples is investigated through the experimental determination of a non-zero off-diagonal effective permeability tensor term κ . The samples are constituted of ferrimagnetic (γ-Fe 2 O 3 ) or ferrom

The purpose of this article is to bring out the nonreciprocity of ferrimagnetic powder loaded composites. We first describe their technology of preparation. Then we briefly recall the principle of the broadband measurement method used to determine th

The permeability tensor of partially magnetized ferrites or composite materials, given by a recent mathematical model developed in our laboratory, is compared with measured one over the 50 MHz–6 GHz frequency range. The characterization method used

Cold-pressed powder compacts in our experiments were prepared from commercial nanopowders of ZnO, Ni, Co and γ‐Fe2O3. A systematic study of the room temperature effective permeability tensor of composite samples made of these nanophases is perform
