“…Transverse M (M IP ) is present when the applied magnetic field perpendicular to the easy axis. The applied magnetic field along the easy axis induces an unusual canting of sublattices A and B into the y direction [26,27]. Given that the canting is brought on by an increase in Zeeman energy, sublattice B must cant more for X = A; as a result, M a > M a' .…”

Van der Waals antiferromagnets (AFMs) provide two-dimensional (2D) platform for spintronic devices with exceptional properties. However, the electric transport features of the magnetic order of van der Waals AFM influenced by different field directions and amplitudes has not been demonstrated systematically. In this letter, we investigate the magnetic texture of the exfoliated van der Waals FePS3, a uniaxial AFM with perpendicular anisotropy, detected by the spin Hall magnetoresistance (SMR). Magnetic field- and temperature- dependent longitudinal magnetoresistance measurements in three orthogonal directions for the exfoliated FePS3/Ptbilayers are conducted. The modulations in the SMR signal enable the separation of two contributions to the SMR, one of which corresponds to the negative signature of AFM SMR caused by in-plane field rotations, and the other of which is caused by canted spins in perpendicular AFM order. Our findings offer great guidance for further research and investigation using SMR approach of the magnetic texture in van der Waals AFMs.

Magnetic fluid shock absorbers (MFSAs) have been successfully utilized to eliminate microvibrations of flexible spacecraft structures. The method of enhancing the damping efficiency of MFSAs has always been a critical issue. To address this, we drew inspiration from the tree frog’s toe pads, which exhibit strong friction due to their unique surface structure. Using 3D printing, we integrated bionic textures copied from tree frog’s toe pad surfaces onto MFSAs, which is the first time to combine bionic design and MFSAs. Additionally, this is also the first time that surface textures have been applied to MFSAs. However, we also had to consider practical engineering applications and manufacturing convenience, so we modified the shape of bionic textures. To do so, we used an edge extraction algorithm for image processing and obtained recognition results. After thorough consideration, we chose hexagon as the shape of surface textures instead of bionic textures. For theoretical analysis, a magnetic field–flow field coupling dynamic model for MFSAs was built for the first time to simulate the magnetic fluid (MF) flow in one oscillation cycle. Using this model, the flow rate contours of the MF were obtained. It was observed that textures cause vortexes to form in the MF layer, which produced an additional velocity field. This increased the shear rate, ultimately leading to an increase in flow resistance. Finally, we conducted vibration reduction experiments and estimated damping characteristics of the proposed MFSAs to prove the effectiveness of both bionic texture and hexagon surface textures. Fortunately, we concluded that hexagon surface textures not only improve the damping efficiency of MFSAs but also require less MF mass.

“…[24] To date, Raman [11,14] and second harmonic generation (SHG) [25] techniques have been used to study the 2D magnetism of atomically thin antiferromagnetic vdW materials. A recent transport measurement using the spin Hall magne-toresistance (SMR) succeeded in measuring the sublattice magnetization of exfoliated FePS 3 , [26] which is another direction for the studies of vdW antiferromagnets. Although they prove practical, there are also limitations, as they cannot provide direct information about the microscopic origin of the antiferromagnetic properties.…”

new class of vdW magnets provides the long-sought-after experimental testbeds of the fundamental Hamiltonians of 2D magnetism: Ising, XY, and Heisenberg models. [6] The first experimental test of the Onsager solution of the Ising model was performed on antiferromagnetic FePS 3 , [7] followed by the discovery of 2D ferromagnetic van der Waals materials such as CrGeTe 3 [8] and CrI 3 . [9] Eventually, the XY and Heisenberg models were subsequently realized using NiPS 3 , [10,11] CrCl 3 , [12] and MnPS 3 , [13][14][15] respectively.The investigation of vdW materials has so far focused on 2D magnetic order phenomena, and much less attention has been paid to their microscopic origin. Typically, the role of orbital magnetism is often neglected since the magnetic orbital moment is supposedly quenched in most 3d transition metal based magnetic materials via so-called crystal field splittings due to the interaction with the surrounding atoms. However, systems with reduced symmetry can, in principle, host sizeable magnetic orbital moments approaching those of the respective free atoms. [16,17] In such a case, the spin-orbit interaction can give rise to new phenomena such as spin-orbit entanglement, a manifestation of direct quantum effects in the condensed matter state. [18] Moreover, FePS 3 is-as we will show-a material whose properties are dominated by strong electron correlations. In spinorbit entangled systems, electron spins and orbital motions Van der Waals (vdW) magnets are an ideal platform for tailoring 2D magnetism with immense potential for spintronics applications and are intensively investigated. However, little is known about the microscopic origin of magnetic order in these antiferromagnetic systems. X-ray photoemission electron microscopy is used to address the electronic and magnetic properties of the vdW antiferromagnet FePS 3 down to the monolayer. The experiments reveal a giant out-of-plane magnetic anisotropy of 22 meV per Fe ion, accompanied by unquenched magnetic orbital moments. Moreover, the calculations suggest that the Ising magnetism in FePS 3 is a visible manifestation of spin-orbit entanglement of the Fe 3d electron system.
