Summary: This study investigates the spin dynamics of PEG-coated Erbium substituted nanocrystalline CoFe2-xErxO4 by FMR spectroscopy, revealing that the optimum doping concentration is x = 0.3. Static magnetic measurements show ferromagnetic behavior in all sample compositions. The enhancement in magnetic properties is attributed to super-exchange interaction, while room temperature FMR spectra confirm ferromagnetic behavior with improved dynamic response.

Summary: We conducted a systematic study on the structural and magnetic properties of LaBa1-xSrxCuFeO5+delta (La -x) and YbBa1-xSrxCuFeO5+delta (Yb-x) ceramic compounds. The experimental results show that the crystal structure, infrared spectrum, surface morphology, and composition of the materials change with different Sr contents. Vibrating sample magnetometry measurements indicate the presence of an antiferromagnetic transition only when x = 0.

Summary: Mg0.5Ni0.5Fe2-xCrxO4 (x = 0.0, 0.2, 0.4, and 0.6) ferrites were synthesized using the solid-state reaction route. The synthesized materials' crystal structure, microstructure, crystallite size, magnetic and resistivity properties were measured using XRD, SEM, FT-IR spectroscopy, VSM, and DC electrical resistivity measurements. The results showed that the synthesis was efficient and resulted in improved crystallite sizes in a single-phase cubic spinel structure. The addition of chromium ions resulted in changes in lattice constant, crystallite size, saturation magnetization, remanent magnetization, and coercivity.

Summary: (Fe1-xGax)92Zr8 amorphous and nanocrystalline alloys with x = 0.15 to x = 0.36 were investigated to improve the magnetic softness of Galfenol-type alloys and evaluate their magnetostrictive properties. It was found that annealing the rapidly solidified ribbons at 823 K for 1 h produced a nanocrystalline structure with body-centered cubic (BCC) Fe-Ga phase crystallization for x = 0.15 to x = 0.26. Beyond x = 0.26, the ribbons crystallized into BCC and a ternary intermetallic phase (ZrFe6Ga6) that negatively affected saturation magnetization, magnetic softness, and magnetostriction coefficient. The alloy with x = 0.26 annealed at 823 K for 1 h exhibited a peak magnetostriction of 10 ppm with saturation magnetization of 110 Am2/kg and coercivity of 260 A/m.

Summary: CaFe2O4 is an S = 5/2 antiferromagnet exhibiting two magnetic orders, with the low-temperature A phase order finding its origins in the freezing of antiphase boundaries created by thermal fluctuations. The magnetic order observed in this material results from a competition between exchange coupling and single-ion anisotropy.

The cubic B1 structure is more stable for x < about 0.75, while the hexagonal structure (B4) is more stable for x > about 0.75. The composition dependent hardness and phase decomposition contribute to the convex shaped hardness curve of Ti1-xAlxN.

Summary: This report uses rigorous calculations based on density functional theory to study the piezoelectric and elastic properties of wurtzite aluminum nitride (w-AlN) with single- and co-alloying by Hf (or Zr) and Sc. The research finds that the (HfSc)0.375Al0.625N and (ZrSc)0.375Al0.625N with stable wurtzite phase have a large piezoelectric coefficient d33 of 49.18 pC/N and 47.00 pC/N, respectively. However, the piezoelectric voltage constant g33 and electromechanical coupling constant k233 of HfAlN, ZrAlN, HfScAlN, and ZrScAlN are smaller than that of ScAlN, which is attributed to the large dielectric constant epsilon 33 of Hf (or Zr) alloying samples. Furthermore, the calculations of internal parameter u and bond angle alpha elucidate the brittle-to-ductile transformation in alloying w-AlN crystal structure. Electronic structure calculations show that the bandgap decreases almost linearly with the increase of alloying concentration, and the Hf (or Zr) alloying compounds become n-type semiconductors due to the existing high-charge states.

Numerical simulations and analysis show that the structure can produce R, G, and B colors with a purity comparable to standard RGB colors, while maintaining efficient transmission efficiency and obtaining a rich variety of structural colors. Additionally, a metallic interlayer is introduced to selectively suppress resonances in the short-wavelength region, improving the purity of the red color.

Summary: Solubility property is of great interest in chemical, physical, pharmaceutical, material, and environmental sciences. Understanding the intrinsic reason behind solubility behavior is a fascinating task. The theoretical relation between binary mutual solubility and liquid-liquid interfacial tension has been derived, where the partitioning of solute molecules between two coexisting liquid phases is determined by the transfer free energy per unit segment for a chain-like solute molecule expressed in terms of solute-solvent interfacial tension. This general theory of solubility is in good agreement with experimental results for binary mutual solubility and molar transfer free energy of solute molecules.

Summary: The influence of ZrOn matrix stoichiometry on the electrical and magnetoresistive properties of Fe-Zr-O nanocomposites has been studied. It was found that the magnetoresistive effect is not observed in composites with oxygen lack, while composites with oxygen excess show magnetoresistive effect and increased resistivity. Magnetoresistivity in composites with oxygen lack only appears after heat treatment. These results can be explained by the difference in the density of localized states in the oxide matrix of the composites and the ratio between two types of conductivity.
