Abstract
Ba 1.5Sr 1.5Co 1Zn 1Fe 23O 41 hexaferrites added with x wt% Bi 2O 3 were successfully prepared, and their phase composition, microstructure, and high-frequency magnetic and dielectric properties were investigated. The results show that the Bi 2O 3 additive leads to the formation of the W-type ferrite phase and a subsequent increase in its proportion, which affects the magnetic and dielectric properties of Z-type hexaferrites. This effect can be explained by the effective medium theory. Furthermore, Bi 2O 3 additives improve the compactness and reduces the grain size. The permeability and permittivity of the samples decrease, but the magnetic and dielectric losses are successfully reduced. For x = 1.5 wt%, the samples have a similar permeability and permittivity, a large miniaturization factor (∼18), a cut-off frequency of about 0.9 GHz, and considerably reduced magnetic and dielectric losses. An appropriate amount of Bi 2O 3 additive improves numerous properties of the Ba 1.5Sr 1.5Co 1Zn 1Fe 23O 41 ferrite, making it a more suitable material for high-frequency miniaturized antennas.
