Summary: CoFe2O4 and CoFe2O4-CoFe composites were synthesized using a simple single-step sonochemical method under atmospheric conditions, allowing easy control of the CoFe content in the composites. Analysis using X-ray and electron diffraction and high-resolution electron microscopy confirmed the formation of CoFe2O4-CoFe composites. High-resolution transmission electron microscopy revealed the presence of core-shell nanostructures in the CoFe2O4-CoFe composites, resulting in enhanced exchange coupling between the soft CoFe and hard CoFe2O4 magnetic phases. The study demonstrates that the magnetic properties of the composites can be tuned by controlling the content of the soft magnetic phase CoFe, thereby adjusting the exchange coupling between the hard magnetic phase CoFe2O4 and the soft magnetic phase CoFe.

Summary: YFeO3 (YFO) thin films were prepared by sol-gel spin-coating technique and annealed at different temperatures. The phase formation, microstructural, optical, photoluminescence, and magnetic properties of the films were investigated. X-ray diffraction analysis showed the formation of hexagonal-YFO phase at 750-800°C and orthorhombic-YFO phase at 850-900°C. The h-YFO films had a homogeneous surface with uniform particle size, while the o-YFO films had larger and irregular particles. The optical band gap and magnetization increased with increasing annealing temperature, and the PL spectra of h-YFO films were redshifted compared to o-YFO films.

Summary: This study reports on a revisited investigation of perovskite-based manganite La0.67Sr0.33MnO3 (LSMO) deposited onto corning-glass (CG) substrates. LSMO films with thicknesses ranging from 35.0-109.7 nm were fabricated using RF sputtering with different deposition times. The films exhibited hexagonal structures with an unmodified R-3c (167) space group. AFM images revealed clusters of monolayer growth. The optical band gap (Eg) showed a direct variation with deposition time, while the resistivity graphs were fitted using the percolation model to understand the electrical transport.

Summary: This article investigates the effect of adding nanoscale TiO2 on the structure and superconducting parameters of high-temperature superconductor YBa2Cu3O7-d (Y123). Polycrystalline Y123 compounds with different percentages of TiO2 were prepared using thermal treatment. X-ray diffraction analysis confirms the presence of Y123 phases in all composite samples. Field-emission scanning electron microscopy analysis shows increased grain size, decreased porosity, and partial melting of grains in TiO2-added samples. AC susceptibility measurement and the four-probe method were used to study the magnetic and electric transport properties, respectively. The observed results indicate that the superconducting transition temperature decreased and the superconducting transition width improved with TiO2 addition, with the sample at x = 1.0 wt.% showing the sharpest increment in superconducting transition temperature, suggesting TiO2 nanoparticles can serve as artificial pinning centers and enhance the connectivity among grains in Y123 ceramic.

Summary: This study investigates the potential of utilizing cobalt ferrite (CF) nanoparticles grown on eggshell membranes (ESM) to address the issue of electromagnetic interference (EMI). CF nanoparticles were synthesized on ESM through a simple carbonization process, and their microwave absorption performance (MAP) at X-band frequency was evaluated. The composite of CF and ESM, called CESM@CF, exhibited a strong RL peak value of -39.03 mm at an optimal thickness of 1.5 mm. The excellent impedance matching and EM wave attenuation of CESM@CF can be attributed to the multiple interfaces, conduction loss, interfacial polarization, and dual influence from both CF and ESM. CESM@CF composite is projected to be an outstanding biomass-based nano-composite for EM wave absorption applications.
