Multifunctionality of AlBaFe12O19/CoZnFe2O4 hybrid nanocomposite: Promising structural, elastic, morphological, compositional, optical, and magnetic properties

A detailed report on the influence of Aluminum doped Barium Hexaferrite (ABH) on structure, elasticity, morphology, composition, and optical and magnetic behavior of hybrid ABH-CZF (AlBaFe12O19)1-x/(CoZnFe2O4) x with X = 0.1, 0.2, 0.3, 0.4 nanocomposites is presented. A new study on the role of ABH in the composite made by the physical mixing method. The composites were characterized by XRD, SEM, EDAX, FTIR, UV, PL, and VSM analysis. XRD confirms the formation of hexagonal and spinel structures in the composite along with their cell volume, lattice parameters, stress, strain, and other structural parameters. Elastic parameters and Debye tem-perature were measured using FTIR. The composite AC 60-40 is found best suited for high-density optical storage devices and as lead-free radiation shielding materials. From the UV analysis, Both the direct and indirect band gap energies are found to be increasing with increasing ABH concentration. The overall structural and optical properties also prove that the material can be used in tunable photonic applications. The refractive index of the composite is between 3.0 and 3.2, which can be used for photo-electrochemical cells, optical detectors, or re-flectors. Magnetic properties examined using VSM showed a decrease in Ms, Mr, and Hc values along with ABH concentration which may be suitable for data storage applications such as rewritable storage hard drives. The maximum values for Ms (7.85 emu/g), Mr (20.44 emu/g), and Hc (2.01 kOe) are found for AC90-10 nano -composite material. By plotting loop width (Delta H) versus magnetization (M), the magnetic interaction between the composite is studied.
