Spontaneous topological Hall effect at room temperature in a van der Waals magnetic semimetal

Hideki Matsuoka, Shun Kajihara, Kanta Endo, Yue Wang, Yoshihiro Iwasa, and Masaki Nakano

Phys. Rev. Materials 10, 014003 (2026) - Published 28 January, 2026

Spontaneous topological magnetic texture formation at room temperature under zero magnetic field is vital for advanced spintronics applications. One of the commonly-used techniques for probing such a topological spin texture is the topological Hall effect (THE), which is induced by the fictitious field generated. Here the authors report observation of THE under zero magnetic field in a van der Waals magnetic semimetal, Cr3Te4. Owing to its high Curie temperature, spontaneous THE survives up to room temperature. Their findings provide profound insights into the emergence of a topological spin texture in a van der Waals magnet, taking a step toward future spintronics applications.

Observation of anisotropy of orbital Hall effect in an epitaxial titanium

Shutaro Karube, Yuta Yahagi, Yoshiaki Saito, Chih-Hsiang Tseng, Ryusuke Hisatomi, Yoichi Shiota, and Teruo Ono

Phys. Rev. Materials 10, 014401 (2026) - Published 7 January, 2026

Anisotropic orbital Hall behavior in epitaxial Ti thin films emerges as a natural consequence of direction-dependent orbital transport. First-principles calculations reveal that the orbital Hall conductivity in Ti(11¯00) differs when electric fields are applied along [0001] versus [112¯0]. Experiments using Ni to probe orbital torque confirm this intrinsic anisotropy, showing corresponding changes in torque generation, and in the critical current required for magnetization switching. These findings uncover orbital-transport anisotropy absent in polycrystalline systems and highlight a fundamental pathway for orbital-driven spintronic phenomena.

Phys. Rev. Materials 10, 015602 (2026) - Published 9 January, 2026

Understanding the fundamental principles of dynamic many-body systems from their temporally and spatially varying pattern images provides valuable insights into living and abiotic matter. Using liquid-crystalline skyrmion arrays as a model system, the authors apply geometric and topological data analysis to uncover their multiscale structure, motion, and shape changes of individual structures. Their approach relies on the Ψ function, a new topological descriptor that distinguishes pure translational dynamics from transformations in soliton geometry or spatial reorganization. This general framework connects image-based analysis with the underlying physical or biological processes. It can be applied to cellular organization, active matter, nanomaterials, and complex self-assembled systems.

Fabrication of microstructured devices of the unconventional superconductor CeCoIn5 for investigations of isolated grain boundaries

S. Mishra, S. M. Thomas, R. McCabe, E. D. Bauer, and F. Ronning

Phys. Rev. Materials 10, 016202 (2026) - Published 7 January, 2026

Grain boundaries strongly influence superconductors by acting as vortex pinning centers and weak links that enable the Josephson effect – a phenomenon central to Josephson junctions, SQUIDs, and phase-sensitive experiments for establishing superconducting order-parameter symmetry. Here, the authors present a practical recipe for isolating and fabricating devices containing single grain boundaries from bulk polycrystalline samples of unconventional superconductor CeCoIn5 using a combination of grain orientation imaging and micromachining. Electrical transport measurements reveal coherence of superconductivity across a grain boundary. This work is an important demonstration that paves the way for the development of phase-sensitive experiments and Josephson-junction based devices for emerging quantum technologies.

Electron magnetic circular dichroism (EMCD) in TEM enables access to the functional magnetic material properties at length scales beyond the reach of X-ray magnetic circular dichroism (XMCD). Here, we use EMCD to probe orbital and spin moments (mL/mS) across the first-order metamagnetic phase transition in FeRh. The evolution of the EMCD-derived magnetic signals and the mL/mS ratio are systematically measured as a function of probe convergence and size, and remain comparable to XMCD down to ~6 nm probe sizes. For more convergent probes, deviations emerge, reflecting enhanced sensitivity to instrumental effects and nanoscale magnetic nonuniformities, highlighting EMCD’s potential for locally resolved studies of functional magnetic systems.

Phys. Rev. Materials 10, 014002 (2026) - Published 9 January, 2026

Electrochemical lithium intercalation in the van der Waals gaps of MoS2 can be used to control its crystal phase and physical properties. Applications include electronic contacts, batteries, neuromorphic computing, and thermal switches. In this work, the authors study the dynamics of the phase transformations upon the removal of lithium from 1T-LiMoS2. By combining single-flake electrochemistry with correlative Raman spectroscopy, they demonstrate that MoS2 remains in a metastable 1T phase even when lithium is electrochemically removed. However, it slowly relaxes back to the thermodynamically stable 2H phase over several days without additional chemical or electrochemical reactions. This delayed transition enables the design of metastable mixed phases in MoS2 through electrochemical intercalation.

Phys. Rev. Materials 10, 015002 (2026) - Published 13 January, 2026

Superconductor/ferromagnet interfaces are fertile ground for emergent phenomena that result from competing interactions. All-oxide heterostructures based in high-Tc superconducting cuprates and half-metallic manganites are especially appealing in this context, and a promising platform for developing superconducting spintronic devices. Based on those heterostructures, the authors realize vertical micro-junctions that show a unusual spin-valve effect, whose polarity can be reversed by temperature. This can be understood considering the interplay between superconducting proximity, spin-dependent scattering, and magnetic exchange effects.

Machine learning interatomic potentials accelerate defect exploration in amorphous silica

Xinpeng Li, Xinjing Guo, Menglin Huang, Xin-Gao Gong, and Shiyou Chen

Phys. Rev. Materials 10, 015003 (2026) - Published 14 January, 2026

Defects in amorphous materials​ are site inequivalent, and each atomic site​ exhibits multiple metastable configurations, making DFT-based​ studies of defect properties computationally expensive. The authors propose a data-efficient approach based on machine learning interatomic potential (MLIP). The training set is built from locally perturbed defect configurations​ at only a few atomic sites. Despite this small dataset, the trained MLIP successfully predicts defect structures and formation energy distributions for all atomic sites across the amorphous systems. A dual-model cross-validation strategy further identifies and refines inaccurate predictions, improving the overall prediction accuracy. Their approach enables efficient, large-scale statistical analysis of defects in amorphous systems.
