Summary: Multi-metal spinel ferrite nanocrystals of Ni0.3Cu0.3Zn0.4Fe1.4Cr0.6O4 were synthesized using sol-gel auto-combustion route. The structural, magnetic, and dielectric properties of the nanocrystals were affected by calcination temperature. The prepared nanocrystals exhibited different crystallite sizes, lattice strains, dislocation densities, saturation magnetizations, retentivities, coercivities, magnetic anisotropies, dielectric constants, dielectric losses, conductivity values, and impedance values at low-frequency range. These nanocrystals have potential applications in capacitors, recording systems, high-frequency devices, and multilayer chip inductors.

Summary: Until recently, multifunctional epoxy nanocomposites (MENCs) have attracted the attention of researchers due to their tunable properties. This study focuses on epoxy/Li0.5Al0.35Fe2.15O4/Al2O3 nanocomposites with varying Al2O3 content. The samples were characterized and it was found that increasing the Al2O3 nanofillers enhances thermal conductivity but decreases thermal stability. The samples also exhibit soft ferrimagnetic behavior. The study explains the interesting results of decreasing electrical conductivity and dielectric properties for the composite samples based on a dual interface nanolayer model.

Summary: In this study, Co-substituted Ni-Zn ferrites were synthesized, and their structural and magnetic properties were investigated. The results showed that Co substitution led to an increase in crystallite size and lattice constant, as well as a suppression of Raman peak intensity and shift towards a lower wavenumber. The dielectric properties and magnetic response of the samples were also affected by Co substitution. At low temperatures, the Co-substituted ferrites exhibited a giant coercivity and high effective magnetocrystalline anisotropy.

Summary: The temperature dependence of two-phonon Raman spectra in BiFeO3 nanocrystals above and below the Neel temperature T-N was studied using a resonant laser excitation line. Anomalous frequency hardening and deviation from anharmonic decay were observed below T-N, indicating the existence of spin-phonon interaction. Magnetic measurements showed the coexistence of antiferromagnetic and weak ferromagnetic phases below T-N, supporting the mean-field approach and suggesting a correlation between two-phonon modes and antiferromagnetic ordering in BiFeO3.

The results showed well-defined layered structure, nanometer-scale grains, and crystalline nature of the thin films. The dielectric properties of the multilayer BaTiO3/NiFe2O4 thin films were influenced by temperature and frequency, and the introduction of the ferrite layer reduced dielectric response and increased low frequency permittivity dispersion.

Summary: We study the effects of magnetic ordering on the Raman modes in nanocrystalline Dy3Fe5O12. The phase purity and nanocrystalline nature of Dy3Fe5O12 were confirmed through various characterization techniques. By investigating the spin-phonon coupling mechanism, we found anomalous behavior in certain phonon modes below TC, which can be attributed to the spin-phonon interaction. Our findings contribute to a better understanding of the spin-phonon coupling mechanism and its impact on the multifaceted properties of nanocrystalline Dy3Fe5O12, as well as potential advancements in spintronic devices.

Summary: In this study, the departure frequency of vapor bubbles during boiling of ferrofluid in a horizontal magnetic field is experimentally investigated. Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
