This paper evaluates two strategies for measuring spin-orbit-torque efficiency in the insulating magnet LiAlFeO, finding that lateral + longitudinal spin-torque ferromagnetic resonance yields a reliable efficiency of ~0.07 while Sagnac interferometry, though sensitive, produces conflicting results likely due to non-magnetic contributions.
This paper presents a machine-learning-assisted spectropolarimetry method that extracts the azimuthal orientations of dipole moments in asymmetric plasmonic nanostructures by simultaneously fitting polarimetric dark-field spectra across multiple analyzer angles, achieving high accuracy that aligns with geometric simulations and electron microscopy data.
This paper reports that extended grinding and air-annealing of graphite nanoflakes induce high-density surface wrinkles, which correlate with the trapping of magnetic flux up to 390 K, suggesting these defects are the source of local room-temperature superconductivity.
This paper presents a spatiotemporal programming strategy using an asymmetric dielectric stack in a dual-floating-gate architecture to enable single-gate-controlled, nonvolatile, and reversible switching between p-n and n-p junction polarities in ambipolar 2D semiconductors, thereby facilitating high-density, multifunctional intelligent hardware.
First-principles calculations reveal that proximity effects in a twisted NbSe/MoSe heterobilayer induce a highly non-uniform charge density wave in the MoSe layer, driven primarily by steric repulsion between selenium atoms across the van der Waals gap.
This paper demonstrates that non-centrosymmetric few-layer graphene polytypes, particularly mixed-stacking tetralayers and asymmetrical rhombohedral structures, exhibit highly efficient infrared up/down-conversion capabilities, enabling the generation of correlated photon pairs for potential applications in fiber-optic systems.
This paper demonstrates that the nonlinear Shubnikov-de Haas effect serves as a highly sensitive, phase-resolved probe for characterizing spin-orbit interaction and distinguishing between different spin-texture regimes in heterostructures, offering a valuable tool for advancing spintronics and quantum technologies.
This paper elucidates the microscopic origin of Rashba coupling in transition metal dichalcogenides by demonstrating that the competition between internal polarization and interlayer hybridization governs spin splitting in bilayers, introducing orbital polarization imbalance as a key order parameter to quantify this asymmetry.
This paper proposes a feasible platform for realizing multiple Majorana zero modes by integrating the superconducting topological crystalline metal ZrRuAs with a ferromagnetic insulator, which leverages mirror symmetry and spin splitting to generate a topological superconducting phase with a Chern number of -2.
This paper demonstrates that plasma screening in driven Weyl semimetals induces highly nonlinear, topological photoresponses that exhibit optical multistability and hysteresis, with broken time-reversal symmetry further enabling helicity-selective chiral photocurrents through tilted Weyl nodes.
