Summary: Nickel-substituted cobalt ferrite nanoparticles were synthesized and characterized. The nanoparticles exhibited a cubic spinel ferrite structure and their magnetic properties were determined. With the increase in nickel doping concentration, the crystallite size and lattice parameters decreased, and the saturation magnetization, remanence magnetization, and coercivity of the nanoparticles decreased as well. These findings suggest that the prepared nanoparticles can be used for data storage device applications.

Summary: In this study, polycrystalline ceramics Bi3ZrVO9, Bi2LaZrVO9, Bi2NdZrVO9, and Bi2SmZrVO9 of the Aurivillius family were prepared through the mixed oxide reaction method. It was found that the grain size in the samples decreases with decreasing bond dissociation energy of the elements with oxygen. The samples exhibited a very large dielectric constant at temperatures >= 350 degrees C and showed a ferroelectric nature, with the dominant conduction mechanism being the correlated barrier hopping (CBH) model.

Summary: In this study, Ba1-xCaxFe12O19 samples were synthesized using sol-gel auto-combustion method, with the maximum calcium solubility observed at 1200 degrees C. The XRD data showed a decrease in lattice parameters and cell volume with increasing 'x', while FESEM images revealed an increase in particle size. Magnetic measurements indicated that the highest saturation magnetization was found in the x = 0.50 sample, with a decrease in coercivity as 'x' increased.

Summary: In this study, Mossbauer spectroscopy and X-ray diffraction were used to investigate the crystal structure and hyperfine interaction parameters of FeBO3 single crystals over a wide temperature range. A theoretical model was developed to describe nuclear resonance transitions in iron atoms, and a technique for correcting Mossbauer spectra was elaborated. The results showed significant effects of additional resonance lines on the FeBO3 spectra, and the study is crucial for the application of FeBO3 crystals in high-tech fields.

Summary: In this study, the existence of vertically heterogeneous thermally induced structural relaxation in amorphous In-Zn-O (a-IZO) thin films was observed using in situ X-ray reflectivity, which has not been previously observed. Thermal annealing was found to influence the electrical performance of the films. These findings are important for the development of a-IZO-based devices.

Summary: Sol-gel autocombustion method was used to synthesize Ni0.7-xZnxMg0.3Fe2O4 nanoparticles with x = 0.1, 0.2, 0.3, 0.4, and 0.5. The synthesized Zn-substituted Ni-Mg ferrite cubic spinel nanoparticles exhibited a cubic spinel type structure, as confirmed by X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy data. Scanning electron microscopy (SEM) analysis showed the microstructure of these ferrites, which were found to have proper stoichiometry without any impurities according to energy-dispersive spectroscopy (EDS) analysis. Vibrating sample magnetometer (VSM) studies revealed that the saturation magnetization and magnetic moment increased with zinc concentration up to x = 0.2, and then decreased for further compositions except x = 0.5.

Summary: The changes in substituted La0.5Sr0.5FeO3_ & gamma; orthoferrite under vacuum annealing in the temperature range of 200-650°C were investigated using X-ray diffraction, Mössbauer spectroscopy, and Raman spectroscopy. The annealing process resulted in a transition from rhombohedral to cubic structure at 650°C. The presence of oxygen vacancies and Fe4+ ions in the local environment of Fe3+ ions contributed to the variations observed in the Mössbauer spectra.

Summary: In this study, aluminum-nickel ferrite nanostructure was synthesized using PVP as a capping operator. The effects of Al3+ substitution on structural, morphological, quantitative, qualitative, and magnetic properties were characterized. The findings showed that with an increase in Al concentration, there was a decrease in average crystal size, development of thermally stable nickel ferrite, and a decrease in overall magnetization due to substitution of Al(3+) ions.

Summary: A series of single-phase nickel-substituted magnesium spinel ferrites were synthesized using the hydrothermal technique, and their morphology, structure, magnetism, and electrochemical properties were investigated. Experimental characterization techniques confirmed the presence of a single-phase spinel structure, with a decrease in lattice parameter and clustering of nanoparticles as nickel concentration increased. Raman and FTIR spectra indicated changes in wave numbers and the shortening of Fe-O bonds. Additionally, the ferrites exhibited increased saturation magnetization, decreased coercivity, decreased specific capacitance, and increased loop size. These ferrites are promising for energy storage applications.
