| Abstract: | Sol-gel auto-combustion technique has been utilized to synthesize Lanthanum (La3+) substituted Sr 4 Ni 2 La x Fe 36-x O 60 (0.00 ≤ x ≤ 0.09 and Δx = 0.03) U-type hexaferrites. X-ray diffraction studies confirmed the single-phase nature the of fabricated materials. The lattice constant "a" was determined to be 5.75 Å, while the lattice constant "c" varied from 112.273 to 112.713 Å with the substitution of La3+ cations. The XRD data analysis revealed the crystalline size ranging from 49 to 73 nm. The microstrain was improved by substituting La3+ in these U-type hexaferrites. FTIR spectroscopy evidenced stretching vibrational peaks in the region (400-600 cm−1), confirming the spectral bands of these hexaferrites. The presence of every metal cation in its specified valence state was evaluated using XPS analysis. Dielectric parameters, including loss factor, dielectric constant, Q-value, reflection loss, and tan loss, have been optimized by these substitutions of La in the hexaferrites. The maximum microwave absorption was achieved with a reflection loss (RL) of −46 dB at 4.5 GHz for x = 0.09. The comparatively smaller reflection loss (−46 dB) makes this composition ideal for microwave absorption applications. [ABSTRACT FROM AUTHOR] |
