A dual-surfactant H-Fe₃O₄ magnetorheological fluid (H-Fe₃O₄@MRF) was prepared by dispersing the modified nanoparticles in dimethyl silicone oil (DSO) with oleic acid (OA) as a co-surfactant. The microstructure and magnetic properties of the hollow nanoparticles were characterized using transmission electron microscopy, scanning electron microscopy, and vibrating sample magnetometry. The magnetorheological (MR) behavior of H-Fe₃O₄@MRF was evaluated using an MCR301 rheometer. A molecular dynamic model was built using LAMMPS to simulate magnetic chain formation, structural evolution under shear, and the impact of nanoparticles hollowness on sedimentation stability. Simulations show that under magnetic fields, H-Fe₃O₄ nanoparticles rapidly form 3D chain structures that reorganize into lamellar patterns during shear flow, significantly improving dynamics yield strength and shear stability. Both experiments and simulations confirm that H-Fe₃O₄@MRF achieves three times better anti-sedimentation stability than conventional solid Fe₃O₄-based fluids.

Here, we report the structural, thermodynamic, and magnetic properties of a novel magnetic material Li₂Co₃Se₄O₁₂ based on x-ray and neutron diffraction, specific heat, magnetization, and x-ray photoelectron spectroscopy measurements. X-ray and neutron diffraction refinements reveal two Co sites Co (1) and Co (2) even though both are in the octahedral environment. While they are not connected along the <em>b</em> and <em>c</em> directions, these octahedra are edge-shared forming the Co (2) – Co (1) – Co (2) trimer chain along the <em>a</em> direction. The magnetic susceptibility exhibits the Curie-Weiss (CW) temperature dependence at high temperatures (above ∼50 K) with the negative CW temperature, a dip centered at T^⁎ ∼ 8.0 K, and an antiferromagnetic transition at T_N = 3.3 K. The specific heat confirms that there is a phase transition at T_N and a hump at T^⁎. The long-range magnetic transition at T_N implies that, in addition to the intra-chain interaction, there is strong inter-chain interaction, which is likely due to polarized SeO₃ bridging between chains. Single crystal neutron diffraction refinement reveals a complex magnetic structure with the angle between Co (1) and Co (2) moments ∼105°. Within the Co (2) – Co (1) – Co (2) trimer, two Co (2) moments are parallelly aligned. Surprisingly, the Co (1) moment (1.92μ_B) is only half of the Co (2) moment (3.96μ_B). There is likely the spin-state change for Co (1) from the high-spin state at T &gt; T^⁎ to the low-spin state at T &lt; T^⁎, causing a dip in the magnetic susceptibility and a hump in the specific heat.

The results reveal that the ground-state properties of zSiGeNRs are highly sensitive to both the chemical composition and the symmetry of edge terminations. Homogeneous symmetric modifications (e.g., 2Cl–zSiGeNR–2Cl, 2F–zSiGeNR–2F, 2H–zSiGeNR–2H) exhibit antiferromagnetic metallic behavior, whereas homogeneous asymmetric ones (e.g., 2F–zSiGeNR–1F, 2Cl–zSiGeNR–1Cl) induce robust half-metallicity. Heterogeneous edge functionalizations further enhance tunability: symmetric configurations display narrow-gap semiconducting characteristics, while asymmetric ones yield half-metallic states, with the direction of edge asymmetry determining the metallic spin channel. The application of a transverse electric field enables reversible transitions between metallic, semiconducting, and half-metallic phases, demonstrating strong electric-field control. Certain asymmetric systems preserve half-metallicity under high fields, indicating excellent stability for spintronic applications. Additionally, width-dependent analysis demonstrates that quantum confinement and edge interactions govern electronic evolution, with asymmetric systems such as 2F–zSiGeNR–1F retaining half-metallicity across a broad width range (<span><math><mrow><msub><mrow><mi>N</mi></mrow><mrow><mi>z</mi></mrow></msub><mo>=</mo><mn>6</mn><mo>−</mo><mn>14</mn></mrow></math></span>).
