Static and Dynamic Magnetic Properties of Polycrystalline Hexaferrites of the Ba2Ni2-xCuxFe12O22 System

The paper presents the results of a study phase composition and main static magnetic characteristics: saturation magnetization, residual magnetization coercive force polycrystalline ferroxplana type hexaferrites Ba2Ni2-xCuxFe12O22 (0 ≤ x 2.0) system. These materials have high permeability are promising for use as substrates antennas radar absorbing materials. It is shown that thermograms initial can be used to quickly assess presence impurity phases in complex oxide ferrimagnets. permittivity spectra textured non-textured composite samples with powder Ba2NiCuFe12O22 hexaferrite measured microwave frequency range. properties obtained composites analyzed. texturing leads an increase operating band absorber RL < −10 dB from 6.1 GHz 8.2 deepening loss minimum −21 −27 dB.
