摘要： Saturation magnetization, magneto-crystalline anisotropy field, and dielectric properties are closely related to microwave devices applied at different frequencies. For regulating the magnetic and dielectric properties of W-type barium ferrites, single-phase Ba$Me_{2}$Fe$_{16}$O$_{27}$ ($Me= {\rm Fe}$, Mn, Zn, Ni, Co) with different \textit{Me} ions were synthesized by the high-temperature solid-state method. The saturation magnetization ($M_{\rm s}$) range from 47.77emu/g to 95.34emu/g and the magnetic anisotropy field ($H_{\rm a}$) range from 10700.60Oe (1Oe=79.5775A$\cdot$m$^{-1}$) to 13739.57Oe, depending on the type of cation substitution in the hexagonal lattice. The dielectric permittivity and dielectric loss decrease with increasing frequency of the AC electric field in the low-frequency region, while they almost remain constant in the high-frequency region. The characteristics of easy regulation and preparation make it a potential candidate for use in microwave device applications.
