Charge-to-spin conversion is critical element for spintronic devices. In most materials, there are several sources of charge-to-spin conversion, which are often challenging to disentangle. Here, Chen et al succeed in disentangling spin Hall and Rashba-Edelstein contributions to charge-to-spin conversion in ultrathin MoTe2 using position dependent measurements of the current-induced spin accumulation.

Chromium sulfur bromide is an air-stable van der Waals magnet, which has a large optical response. Here, Smolenski et al find a large exciton binding energy CrSBr, which they attribute to localization due to the quasi one-dimensional electronic bands.

A cocktail of experiments and theory provides a way of revealing complex patterns in magnetic materials, including some textures that can identify the systems as members of an elusive class known as axion insulators.

Magnetic phases that are stabilized by quantum fluctuations in low dimensions are rare. A thickness-dependent crossover from three-dimensional antiferromagnetism to a two-dimensional vestigial nematic state that is driven by fluctuations has now been observed.

van der Waals magnets can be arranged into twisted heterostructures, with the twisting leading to the formation of new magnetic phases. Here, Li, Sun, and coauthors show via NVcentre based magnetometry small angle twisted double trilayer CrI₃ exhibits a co-existing, hybrid magnetic phase with distinct phase transition temperatures.

Surface magnetic order could precede bulk order, but detecting such a separation necessitates experimental probes sensitive to both surface and bulk phase transitions. Here, using second harmonic generation, the authors propose that this situation is realized in a van der Waals antiferromagnet CrSBr.

Optical second-harmonic waves are generated from the electric quadrupole contribution in a centrosymmetric magnetic Weyl semimetal Co₃Sn₂S₂. Two magnetic orders and phase transitions are explored in temperature-dependent rotational anisotropy measurements by second-harmonic generation.

By carefully inducing twists or lattice stacking offsets between two adjacent van der Waals crystals, a superlattice potential can be introduced. This Moire lattice offers an incredibly rich physics, ranging from superconductivity to exotic magnetism, depending on van der Waals materials in question. Here, Du et al. study the magnetic domains in twisted CrI₃, and show that despite this ___domain structure, spin fluctuations are spatially homogenous.

Exciton dynamics can be strongly affected by lattice vibrations through electron-phonon (e-ph) coupling. Here, the authors show the presence of strong e-ph coupling in bilayer CrI₃ and observe a Raman feature with periodic broad modes up to the 8th order, attributed to the polaronic character of excitons.

A moiré potential may play a role in determining the magnetic properties of a two-dimensional homo or heterostructure. Now, non-collinear spin structures are observed in twisted double bilayer CrI₃, providing a platform to engineer unusual magnetic textures.

In twisted 2D materials, spontaneous lattice reconstructions mean that twist angle alone provides an incomplete description. Here, using electron diffraction, the authors show that the displacement field in twisted bilayer graphene can be described as a superposition of three periodic lattice distortion (PLD) waves with wavevectors oriented at 120° from each other, forming a “torsional" PLD.

Antiferromagnetism has a vanishing total magnetization and thus is extremely challenging to manipulate. Now, circularly polarized light is shown to efficiently detect, induce and switch a unique class of antiferromagnets.

Jing Wang, Fengchun Zhang and colleagues report the results of a genome-wide association study of primary Sjögren's syndrome, a common autoimmune disease. They confirm associations in the STAT4, TNFAIP3 and HLA regions and identify a new susceptibility locus in the GTF2I region at 7q11.23.

Correlated quantum states in free-standing two-dimensional materials are susceptible to defects and thermal disorder. Here, the authors demonstrate two-dimensional ordered charge density wave states above room temperature in clean interleaved polytype heterostructures of a van der Waals material.

Certain materials without inversion symmetry may allow for a nonlinear anomalous Hall effect with conserved time reversal symmetry. Here, the authors report an extremely large c-axis nonlinear anomalous Hall effect in the non-centrosymmetric T_d phase of MoTe₂ and WTe₂ without intrinsic magnetic order that is dominated by extrinsic scattering.

Characteristics of spin waves in recently discovered two-dimensional (2D) Ising ferromagnets are still lacking. Here, Jin and Kim et al. report Raman resonance evidence of two sets of surface spin waves in the 2D honeycomb ferromagnet CrI₃.

Stacking and twisting two-dimensional materials has led to the observation of a variety of electronic phenomena. Now, magnetic behaviour that is distinct from anything seen in individual layers is induced by a moiré pattern in double bilayer chromium triiodide.

The authors use optical spectroscopy to show that RbFe(MoO₄)₂ hosts a ferro-rotational phase. This is the final form of ferroic order to be observed.

Non-pollen palynomorph data from the western-central Nile Delta region indicates the abundant presence of 7,000 year-old animal micro-fossils such as hair and dung, suggesting that early herders were present in the area prior to widespread agriculture.

The impulsively driven antiferromagnetic Mott insulator is a model quantum many-body system predicted to realize exotic transient phenomena, however its exploration in far-from equilibrium regimes remains experimentally challenging. Here, the authors use a combination of second harmonic optical polarimetry and coherent magnon spectroscopy to investigate the ultrafast non-equilibrium dynamics of the Mott insulator Sr₂IrO₄ and find evidence of a far-from-equilibrium critical regime where static and dynamic critical behaviour decouple and which could be present in a number of other quantum materials.

The authors present the reconstruction of the Sendai Virus N-RNA complex at atomic resolution, including the helical part and a clam-shaped joint, resolved to 2.9 and 3.9 Å respectively, via cryo-EM. They also demonstrate the presence of an additional, ring like structural motif stabilising Nprotein interactions.

Shan et al. describes the high-resolution structures of Nucleoprotein in two different oligomeric states and four different higher-order helical structures. They further describe the structural rearrangements required to transition between the different helical assemblies obtained, highlighting the basis for structural plasticity among different MuV nucleocapsids.
