RETRACTED: Studies of the Electrodynamic Parameters of a Powdered Material Depending on the Fractional Composition in the Frequency Range of 8-12 Ghz

Abstract

This article describes a method for measuring the dielectric constant and magnetic permeability of alumina powder (corundum) in the frequency range of 8-12 GHz. The results of studies of permeability and permittivity using a segment of a coaxial transmission line depending on the size of corundum particles are presented.

Temperature induced structural and polarization features in BaFe12O19

“…Barium hexaferrite (BaFe 12 O 19 ) belongs to the family of M-type ferrites, [5][6][7][8] which are characterized by significant variations in their physical properties depending on the chemical composition. [9][10][11] The ease of their synthesis, high corrosion resistance and stability of properties make hexaferrites attractive, for example, for usage as electromagnetic absorbers and permanent magnets for magnetic storage media.…”
