Summary: The study on Ti65 titanium alloy sheet revealed anisotropic properties in terms of tensile strength, yield strength, and creep endurance between transverse direction (TD) and rolling direction (RD). The orientation of grains and crack initiation sites also showed distinct differences during the creep process. Factors contributing to this anisotropy include changes in Schmid factors values and differences in creep mechanisms between TD (grain boundary sliding) and RD (dislocation slip). It is important to fully consider the anisotropy of Ti65 sheet to enhance structural efficiency in engineering design and application.

Summary: The study theoretically explored the ultrafast propagations of spin waves in antiferromagnetic Bloch-type domain walls and found that the dispersive relation of these spin waves shows extremely high group velocity without any forbidden gap. The results offer guidance for the development of ultrafast information signal processing in nanoscale magnonic circuits composed of antiferromagnetic domain walls.

Summary: The study reports the detection of the average Neel vector orientation in polycrystalline NiO via spin Hall magnetoresistance (SMR), and reduces the critical magnetic field required to reach a saturation of the SMR signal by applying strain through a piezo-electric substrate. The results show that polycrystalline NiO exhibits a positive sign of the in-plane magnetostriction. This method of anisotropy-tuning provides an energy-efficient, on-chip alternative to manipulate a polycrystalline antiferromagnet's magnetic state.

Summary: This study reports new ferromagnetic high damping materials of FeGaMo alloys with different Mo contents. Among these alloys, the alloy with 2 at% Mo content exhibits the best damping capacity. As the Mo content increases, the precipitation of Mo-rich phases restricts the movement distance of domain walls, leading to a decrease in damping. This work provides valuable insights for the design and research of new ferromagnetic high damping materials in the future.

Summary: This study investigates the rolling and tensile behaviors of Ti-4Al-0.005B alloy using electron backscatter diffraction (EBSD) technique. The results show that different rolling and annealing processes significantly affect the grain refinement and texture formation of the alloy, with the 990 + 550 degrees C rolled sample exhibiting the best mechanical properties.

Summary: This study investigated the formation and magnetic properties of ThMn12-type Ce1+xFe11Ti samples, revealing the formation of twin boundaries and achieving grain refinement by adjusting chemical composition and annealing temperatures. The magnetostrictive behavior of the CeFe11Ti-phase was also studied, showing an M-2 behavior near the Curie temperature. Additionally, magnetic characterizations under hydrostatic pressure and after hydrogenation demonstrated a slight reduction in anisotropy field, consistent with the observed increase for the hydrogenated compound.

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.

Summary: Through a comprehensive Monte Carlo investigation, this study demonstrates how the mechanical properties of self-assembled magnetic nanocubes can be intrinsically controlled by the nanoparticle magnetocrystalline anisotropy (MA), as well as by the superstructure shape anisotropy. Low MA-to-dipolar energy ratio favors isotropic mechanical superstructure stabilization, while a high ratio yields magnetically blocked nanoparticle macrospins.

Summary: Through micromagnetic simulations and analytical modeling, it has been found that Neel walls can be formed even in the absence of a Dzyaloshinskii-Moriya interaction, but with uniaxial in-plane magnetic anisotropy. The ability to switch between Bloch and Neel walls can be achieved via modulation of both in-plane and perpendicular magnetic anisotropy, opening up possibilities for electric field control of domain wall type with small applied voltages.

Summary: The study investigates the magnetic properties, magnetoimpedance, and field sensitivity of rapidly solidified ribbons with different nonmagnetic elements. The saturation magnetization was found to vary with the type of element added, with the highest value for Cu and the lowest for Al. Magnetoimpedance ratios showed different peak behaviors at different frequencies, indicating the presence of stronger magnetic anisotropy in Al-containing ribbons. The study also validated the variations in magnetoimpedance response with the formation of soft magnetic phase and development of anisotropy due to the replacement of boron with an additional element.

Summary: The effect of unidirectional and cross rolling on Mg-Ga alloys was evaluated, showing that cross rolling improves grain refinement and ultimate tensile strength but decreases elongation, while Ga addition weakens the basal texture. After heat treatment and hot rolling, corrosion rate of the alloys significantly reduced, but cross-rolled samples exhibited higher corrosion than heat-treated and unidirectionally rolled samples. Additionally, the alloys showed lower hemolysis percentages compared to pure magnesium and as-cast alloys, yet they still exhibited hemolytic properties.

Summary: The texture evolution and dislocation density in Al-Mg alloys during uniaxial tensile deformation were investigated using neutron diffraction experiment. The (001) and (111) duplex texture were observed in Al-Mg alloys under low strain rate (1.33 x 10-5 s-1). The differences in pole density at (001) and (111) orientations depended on the content of Mg addition. The (001) deformation texture was developed from initial (001) cube texture, especially in alloys with low Mg addition and pure Al sample. In alloys with high Mg addition, the development of (111) texture was clearly presented. An increase in Mg addition induced larger dislocation density during deformation in correlation with the formation of (111) deformation texture.
