We report the observation of magnetoresistance (MR) that could originate from orbital angular momentum (OAM) transport in a permalloy (Py)/oxidized Cu (Cu^{*}) heterostructure: Rashba-Edelstein magnetoresistance. The dependence MR depends on relative angle between induced OAM and magnetization similar fashion as spin Hall Despite absence elements with large spin-orbit coupling, we find sizable ratio, which is contrast to conventional requires heavy elements. Through Py thickness-dependence...
In 2D magnets, interlayer exchange coupling is generally weak due to the van der Waals layered structure but it still plays a vital role in stabilizing long-range magnetic ordering and determining properties. Using complementary neutron diffraction, magnetic, torque measurements, complete phase diagram of CrPS4 crystals determined. shows an antiferromagnetic ground state (A-type) formed by out-of-plane ferromagnetic monolayers with along c axis below TN = 38 K. Due small anisotropy energy...
The long-range magnetic ordering in frustrated systems is stabilized by coupling moments to various degrees of freedom, for example, enhancing anisotropy via lattice distortion. Here, the unconventional spin-lattice coupled metamagnetic properties atomically-thin CrOCl, a van der Waals antiferromagnet with inherent frustration rooted staggered square lattice, are reported. Using temperature- and angle-dependent tunneling magnetoconductance (TMC), complementary torque first-principles...

We studied the effect of hydrostatic pressure on magnetic properties highly anisotropic van der Waals ferromagnetic metal ${\mathrm{Fe}}_{3}\mathrm{Ge}{\mathrm{Te}}_{2}$ (FGT) with field applied along easy axis. The paramagnetic-to-ferromagnetic transition occurs at Curie temperature ${T}_{c}=180\phantom{\rule{0.16em}{0ex}}\mathrm{K}$ ambient pressure, and ${T}_{c}$ decreases monotonically by up to 15 K as increases 1.44 GPa, while magnetization is suppressed pressure. By using high-pressure...
The recently synthesized two-dimensional van der Waals (vdW) ferromagnet 1T-${\mathrm{MnSe}}_{2}$ has attracted great attention due to its room-temperature ferromagnetism. By using ab initio quantum transport simulations with noncollinear spins, we demonstrate a monotonic increasing (decreasing) tendency of the angle-resolved tunneling magnetoresistance (spin-transfer torque) graphene layer number n in ${\mathrm{MnSe}}_{2}$/n-layer graphene/${\mathrm{MnSe}}_{2}$ (n = 1--4) vdW magnetic...
The spin switching and exchange bias effect were investigated in the rare earth orthoferrite SmFeO3 composed of two antiferromagnetically coupled sublattices Sm3+ Fe3+ with canted ferromagnetic moments a temperature induced single crystal was observed. found to be modulated by exerting different magnetic fields below compensation ([Formula: see text]). This could explained as changes energy barrier related magnetization direction under fields. In meantime, coercivity displayed strong...

With the continuous development of communication technology, microwave frequency used has been extended to 24∼30 GHz or even higher. Thus, for research on absorption materials, commonly 2∼18 range might no longer be enough. More studies properties in a higher band are necessary. In this work, we report several soft magnetic composites up 40 GHz. Magnetic materials such as iron, Y2Fe16Si, Ce2Fe17N3−δ, and La2Fe4Co10B micron powders which display excellent GHz, investigated. Within 2∼40...
To achieve accurate and rapid measurement of the hydrophobicity class (HC) composite insulators, an intelligent spray image recognition technique based on light‐weight convolutional neural networks (CNN) is proposed in this paper. A data set contains clean, contaminated aged insulators with various illuminations, shooting angles distances, about 10 400 images shed surface were collected by tests augmentation. Five classification models established different CNNs, including GoogLeNet,...

Rare-earth transition-metal (R-T) intermetallic compounds are emerging as competitive candidates for novel microwave absorption materials (MAMs) since they show high magnetization and tunable easy directions (EMDs). In this work, Y2(Co1−xFex)17 (0 ≤ x 0.3) with the Th2Ni17 hexagonal structure were prepared purpose of tuning EMDs. As increases, EMDs change from ab-plane &lt; 0.0329) to cone (0.0329 0.038) then c-axis direction (0.038 0.3). Furthermore, it was found that extremely cutoff...
The pivotal role of magnetic anisotropy in stabilising two-dimensional (2D) magnetism has been widely accepted, however, direct correlation between and long-range ordering the 2D limit is yet to be explored. Here, using angle- temperature-dependent tunnelling magnetoresistance, we report unprecedented metamagnetic phase transitions atomically-thin CrOCl, triggered by easy-axis flipping instead conventional spin flop mechanism. Few-layer CrOCl devices various thicknesses consistently show an...
