Summary: We propose a systematic method for generating symmetry-adapted magnetic structures to analyze complex modulated magnetic structures. The method extends the generation scheme based on multipole expansion, which was previously only applicable for k = 0. By mapping the multipole magnetic alignments to the periodic crystal structure with the phase factor for wave vector k, symmetry-adapted magnetic structures with ordering vector k can be obtained. This method provides all magnetic bases compatible with irreducible representations under a k group for a given crystal structure and wave vector k.

Summary: According to previous theoretical work, researchers have discovered that the binary oxide CuO can become a room-temperature multiferroic material by applying pressure. They confirmed this by neutron diffraction, showing that the multiferroic phase in CuO can reach 295 K with the application of 18.5 GPa pressure. They also developed a spin Hamiltonian based on density functional theory and employing superexchange theory, which was able to reproduce the experimental results. This study provides stimulus for developing room-temperature multiferroic materials using alternative methods, such as epitaxial strain, based on existing low temperature compounds, for tunable multifunctional devices and memory applications.

Summary: Metal thiocyanate perovskite-analogues are a promising class of materials that may exhibit interesting magnetic properties. In this study, we investigated the magnetic properties of a metal thiocyanate framework Cr[Bi(SCN)(6)]·xH(2)O and found that it undergoes long-range magnetic order at low temperature. The unique structure and frustrated antiferromagnetic interactions of this material suggest that further exploration in the design of metal thiocyanate perovskite-analogue structures may lead to the discovery of novel frustrated magnetism.

Summary: A structural transition from a cubic phase to a tetragonal phase was observed in non-centrosymmetric oxyfluoride Co3Sb4O6F6 at around 180K. The transition was confirmed through specific heat, magnetization, and dielectric measurements, and a magnetic structure analysis revealed a transition from a paramagnetic phase to a G-type antiferromagnetic phase at around 67K.

Summary: The antiferromagnetic phase transition of Ce(Cu1-xCox)(2)Ge-2 system was investigated, showing a reduction in Ce moment size with Co-doping but no change in magnetic structure. An incommensurate magnetic propagation vector was observed for x = 0.05, while for x = 0.2, there was no long-range magnetic ordering. These results indicate reduced ordered state magnetic moments of Ce3+ ion by Kondo screening and the presence of short-range magnetic correlations.

Summary: Spin-to-charge conversion is a crucial process in spintronics, and this study demonstrates effective spin-to-charge conversion in thermally evaporated chromium thin films. Comparisons with sputtered Pt films show comparable conversion effects, and the opposite sign of the signal indicates a negative spin Hall angle for chromium. The study also reveals the influence of strain state on the conversion efficiency and suggests the possible impact of spin density wave antiferromagnetism in chromium.

Summary: The kagome metal CoSn has been studied and shown to have flat electronic bands, but electronic instabilities are not realized due to the complete filling of the bands. By replacing Sn with In in CoSn1-xInx, the chemical potential is moved into the flat band region, resulting in the emergence of antiferromagnetic order. This work provides clear evidence that chemically manipulating flat bands in bulk crystals can control correlated ground states.

Summary: The study reports on high-temperature crystallographic structure, magnetic and physical properties of chemically B-site disordered PBFW solid solutions, showing a strong spin-lattice coupling around the antiferromagnetic phase transition temperature and presence of magnetoelectric coupling near the ferroelectric transition temperature. Additionally, nanoclusters of PBFW exhibit ferrimagnetic and antiferromagnetic order, supported by EPR and Mossbauer spectroscopic studies which indicate Fe+3 state and B-site disorderliness.

Summary: The binary T-X phase diagram of salicylic acid and benzoic acid was experimentally determined, showing two crystalline solid solutions with solid-state miscibility limits of 10.9 mol% and 82.5 mol% benzoic acid in salicylic acid at 25 degrees Celsius. The eutectic composition of 60.0 mol% benzoic acid in salicylic acid at a eutectic temperature of 112.69 degrees Celsius was also determined. Non-linearity in the Tammann plot was observed due to the temperature dependence of the solvus and compositional non-uniformity in the material.

Summary: By using X-ray and neutron powder diffraction, magnetization measurements, and Fe-57 Mossbauer spectroscopy, the structural and magnetic properties of Sr1-xBaxFeO2F were investigated. The results showed the random occupancy of Sr and Ba atoms at the A-cation site and the statistical distribution of O and F at the anionic sublattice. The magnetic structure was determined to be a G-type antiferromagnetic arrangement with Fe3+ moments oriented along the c axis.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
