| description | In this research, we reported on the formation of highly porous foam SrTiO<sub>3</sub>/NiFe<sub>2</sub>O<sub>4</sub> (<sub>100−x</sub>STO/<sub>x</sub>NFO) heterostructure by joint solid-state and sol-gel auto-combustion techniques. The colloidal assembly process is discussed based on the weight ratio x (x = 0, 25, 50, 75, and 100 wt %) of NiFe<sub>2</sub>O<sub>4</sub> in the <sub>100−x</sub>STO/<sub>x</sub>NFO system. We proposed a mechanism describing the highly porous framework formation involving the self-assembly of SrTiO<sub>3</sub> due to the gelation process of the nickel ferrite. We used a series of spectrophotometric techniques, including powder X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), N<sub>2</sub> adsorption isotherms method, UV-visible diffuse reflectance spectra (UV-Vis DRS), vibrating sample magnetometer (VSM), and dielectric measurements, to investigate the structural, morphological, optical, magnetic, and dielectric properties of the synthesized samples. As revealed by FE-SEM analysis and textural characteristics, SrTiO<sub>3</sub>-NiFe<sub>2</sub>O<sub>4</sub> nanocomposite self-assembled into a porous foam with an internally well-defined porous structure. HRTEM characterization certifies the distinctive crystalline phases obtained and reveals that SrTiO<sub>3</sub> and NiFe<sub>2</sub>O<sub>4</sub> nanoparticles were closely connected. The specific magnetization, coercivity, and permittivity values are higher in the <sub>75</sub>STO/<sub>25</sub>NFO heterostructure and do not decrease proportionally to the amount of non-magnetic SrTiO<sub>3</sub> present in the composition of samples. |
