초록
Na-Ta ions co-doped M-type barium ferrites, BaFe12-2x(NaTa)xO19, were synthesized at low temperature by the solid-state method. Na-Ta ion could occupy crystalline sites but not change the phase formation of barium ferrite. SEM images showed that samples had the regular and hexangular shape with 1-2 μm size. With the increase of Na-Ta, saturation magnetization (Ms) obviously decreased from 57.5 emu/g to 37.6 emu/g, and the coercivity (Hc) decreased from 4156 Oe to 2069 Oe. For dielectric properties, the real part permittivity (ε') increased when x from 0.0 to 0.3, reaching the maximum value in a range frequency of 10 MHz-500 MHz, while decreasing when x=0.4. This material would be applied in electronic devices using LTCC technology.
