Summary: The effects of different parameters of spark plasma sintering (SPS) on LiNiZn ferrite ceramics were investigated. Compared with traditional sintering, SPS resulted in finer, more uniform grains, denser structure, higher saturation magnetization, and lower ferromagnetic resonance linewidth. The cation distribution was analyzed and a method of judging specific saturation magnetization was proposed. SPS can effectively improve the magnetic properties of ferrite ceramics and provide an alternative pathway for high-performance soft magnetic ferrite.

Summary: In this study, single phase Sm doped Co-ferrites nanoparticles were synthesized and characterized, with the saturation magnetization and coercivity field decreasing as the concentration of Sm3+ increased. The cation distribution was found to correspond to a partially inverted ferrite, and the magnetocrystalline anisotropy energy was determined from hysteresis curves. The results were in close agreement with the experimental results due to the presence of superparamagnetic and thermally blocked nanoparticles.

In this study, CoCrCexFeO samples with different compositions were synthesized using the sol-gel auto-ignition process. The results showed that increasing cerium concentration led to changes in the lattice lengths and the substitution of Ce3+ for Fe3+. The samples exhibited a narrow size distribution with nanoparticles approximately 50 nm in size. Additionally, the substitution of Ce3+ reduced the saturation magnetization and increased the coercive field, making the samples suitable for permanent magnets.

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.
