摘要:
In this study, nanocrystalline ZnAl2O4 (ZA) were introduced to Z-type barium hexaferrite (Co(2)Z) and the effects of ZA addition upon the crystal-phase composition, microstructure, permeability and permittivity as well as losses characteristics over a wide frequency range of 10 MHz-1 GHz have been systematically investigated. With increasing ZA content (x) from 0 to 15 wt%, the permeability mu' at low frequencies decreased from 12.0 to 4.3, while the permittivity epsilon' was decreased from 27.4 to 10.7. Correspondingly, the frequency stability of permeability and permittivity were improved and the losses were effectively reduced. When x is in the range of 5-10 wt%, the magnetic loss tan delta(mu) is in the order of 10(-2) and the dielectric loss tan delta(epsilon) is in the order of 10(-3) at 300 MHz, which is lower by one order of magnitude compared with that of undoped Co(2)Z. The modified magnetic and dielectric properties are closely related to the changing phase composition and microstructure. (C) 2017 Author(s).
