Synthesis and characterization of BaFe12O19-CoFe2O4 ferrite composite for high-frequency antenna application

Hard Ferrites for High Frequency Antenna Applications

“…For high-frequency antenna applications, Polley et al created a BaFe12O19-CoFe2O4 ferrite composite [49]. Nanocomposites were synthesized by precipitation method.…”

Tuning the Structure, Magnetic, and High Frequency Properties of Sc‐Doped Sr0.5Ba0.5ScxFe12‐xO19/NiFe2O4 Hard/Soft Nanocomposites

“…Thus, it was noted that the increased magnetic behavior was dominated by interfacial spin interaction between the two magnetic phases and the material could be a good candidate for microwave applications. Moreover, numerous composites of others soft/hard ferrites, such as Ni 0.5 Zn 0.5 Fe 2 O 4 /BaFe 12 O 19 , [24] NiFe 2 O 4 /SrCo 0.2 Fe 11.8 O 19 , [25] Ni 0.6 Zn 0.4 Fe 2 O 4 /SrFe 12 O 19 , [26] SrFe 12 O 19 /FeCo, [27] BaFe 12 O 19 /CoFe 2 O 4 , [28] Mn 0.6 Zn 0.4 Fe 2 O 4 /Sr 0.85 Ba 0.15 Fe 12 O 19 , [29] Ni 0.5 Zn 0.5 Fe 2 O 4 /SrFe 12 O 19 , [30] SrFe 12 O 19 /Ni 0.5 Zn 0.5 Fe 2 O 4 , [31] BaFe 12 O 19 /CoFe 2 O 4 , [32] Li 0.3 Co 0.5 Zn 0.2 Fe 2 O 4 /SrFe 12 O 19 , [33] and (Mn 0.8 Mg 0.2 Fe 2 O 4 ) (1-x) /(BaZn 0.15 Al 0.15 Fe 11.7 O 19 ) x . [34] It has been examined that the high coercive field (H c ) and high saturation magnetization (M s ) could be accomplished via exchange coupling the hard and soft phases to each other.…”
