“…The decrease in a , c , and V could be attributed to the substitution of a smaller ionic radius of La 3+ ( r La 3+ = 1.172 Å) for a larger one of Ba 2+ ( r Ba 2+ = 1.49 Å). 37 A similar phenomenon could be observed not only in the rare‐earth elements doped in the strontium Z‐type hexaferrite (Sr 3− x R x Co 2 Fe 24 O 41 ), 37 but also in the M‐type (Ba 1− x La x Fe 12 O 19 ) 38,39 and W‐type (Sr 1− x La x Co 2 Fe 16 O 27 ) 40 hexaferrites.…”

Controlling material structure and its electromagnetic properties, including complex permittivity and permeability, could enhance the microwave absorption performance of the material in terms of reflection loss and effective absorption bandwidth. In this study, La-substituted barium hexaferrite, Ba 3−x La x Co 2 Fe 24 O 41 (x = 0, 0.1, 0.3, and 0.5) compounds were successfully prepared using the solid-state reaction method, and their corresponding microstructures, static magnetic properties, and electromagnetic features in 2-18 GHz were investigated. The doping of La content increased saturation magnetization, coercivity, and remnant magnetization. The Ba 2.7 La 0.3 Co 2 Fe 24 O 41 epoxied sample with 3.5 mm thickness possessed an excellent microwave absorption of −47.3 dB at 3.52 GHz, and its corresponding effective absorption bandwidths were 3.75 GHz (2.25-6 GHz) and 0.57 . It is shown that doping with various La concentrations on Ba 3 Co 2 Fe 24 O 41 can be used as an effective technique to tune the performance of microwave absorbers based on barium hexaferrite.
