“…The Fe 3+ ions can be replaced by an assortment of trivalent cations such as Sc 3+ , In 3+ and Al 3+ etc. [5,6], or divalenttetravalent cations pairs such as La-Co, Co-Ti, Ni-Ti and so on [7][8][9]. In our research, we chose Na+ ion and Ta 5+ ion to co-doped Fe 3+ ion in M-type barium ferrites at low temperature, to study the structure and magnetic properties.…”

Na-Ta ions co-doped M-type barium ferrites, BaFe 12-2x (NaTa) x O 19 , 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 (M s ) obviously decreased from 57.5 emu/g to 37.6 emu/g, and the coercivity (H c ) 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.
