Summary: In this study, cobalt-modified brownmillerite KBFO polycrystalline was synthesized through solid-state reaction. The Co substitution led to a decrease in optical bandgap energy and a shift in Raman peaks towards lower wavenumber. Additionally, the dielectric constant and dielectric loss of KBFCO decreased at room temperature compared to KBFO, indicating a reduction in oxygen migration and modification in response to vibrational modes.

Summary: In this study, zinc cobalt ferrite nanoparticles were synthesized using the co-precipitation method, and the effect of processing parameters on the microstructure, magnetic properties and hyperthermia performance of the nanoparticles was investigated. The results showed that increasing the calcination time and temperature led to an increase in particle size and magnetic properties. The nanoparticles synthesized at 550 degrees C for 2 hours exhibited the highest heating efficiency in hyperthermia. The concentration of nanoparticles in the ferrofluids also had a significant impact on the heat generation, with the highest specific loss power values observed for ferrofluids containing 5 mg/ml of nanoparticles synthesized at 550 degrees C for 2 hours.

Summary: Co1-xZnxFe2O4 nanoparticles (0 <= x <= 1) were synthesized via a green sol-gel combustion method, and their characteristics were studied using various techniques. The nanoparticles showed high crystallinity and exhibited a cubic Fd-3m structure. The presence of cobalt, zinc, iron, and oxygen in the samples was confirmed through EDS analysis. Raman spectra revealed the preferential location of Zn ions in T sites for low Zn concentrations. The magnetic properties of the nanoparticles were discussed based on the Raman results, showing an increase in magnetization with increasing Zn content for x < 0.5. Co ferrite doped with 30% Zn exhibited the highest SAR values, which increased linearly with H from 20 to 60 kA/m.

Summary: The present study focuses on the low temperature synthesis of In3+ doped cobalt ferrite using sol-gel auto-combustion method. X-ray diffraction analysis confirms the formation of single-phase cubic spinel structure. FE-SEM images show the well formation of spherical grains with an average size of 36 nm. The saturation magnetization decreases with In3+ doping due to the decreasing A-B interaction, and the dielectric constant also decreases.
