This paper experimentally demonstrates that orbital-to-charge conversion via the inverse orbital Hall and Rashba effects dominates over spin-related mechanisms in metallic and semiconductor heterostructures, revealing significant signal enhancements in oxidized copper and distinct orbital diffusion behaviors in titanium and germanium to advance the field of orbitronics.
This study systematically quantifies the cubic magnetocrystalline anisotropy in MnSi and FeCoSi single crystals, revealing that specific low cobalt concentrations in FeCoSi generate sufficient anisotropy to controllably stabilize a low-temperature skyrmion lattice, thereby identifying it as the first chiral metallic system where such a phase is induced by cubic anisotropy.
This paper establishes a unified Poisson Bracket framework for non-collinear antiferromagnetic spin-torque oscillators that utilizes a Terminal Velocity Motion perspective to analytically resolve rapid transient dynamics and hysteretic excitation, while identifying a "Rigid-Body Breaking" mechanism to explain sub-critical current mismatches.
This study demonstrates the on-surface synthesis of atomically precise 2D lateral heterostructures combining graphene nanoribbons and graphdiyne networks via sp-sp2 hybridization, revealing a bromine-mediated formation mechanism and showing that the resulting junction enables voltage-tunable spatial current separation for next-generation all-carbon nanoelectronics.
This paper investigates the dominant energy relaxation mechanisms in fluxonium qubits using a circuit-based capacitive dielectric loss model, revealing that while a fluorine-based wet treatment slightly improves the effective capacitive quality factor by reducing metal-substrate interface loss, it does not address the primary source of loss in these devices.
This study demonstrates a geometry-tunable platform for Bi2Te3 Corbino nanoplates, where a Te-rod-templated growth method enables the observation of enhanced magnetic edge contrast driven by the coupling between inner and outer edge channels as the pore size decreases.
This study theoretically predicts the existence of stable three-dimensional carbon allotropes derived from - and -graphyne via interlayer acetylene bridging, which form fully $sp$- hybridized networks with distinct anisotropic mechanical, electronic, and optical properties confirmed by density functional theory and ab initio molecular dynamics simulations.
This paper introduces and validates the "koopmon" method, a novel quantum-classical Hamiltonian model based on Koopman wavefunctions that successfully captures correlation effects and accurately reproduces fully quantum dynamics in Rashba spin-orbit coupling systems, outperforming conventional Ehrenfest approaches particularly in orbital dynamics and harmonic potential scenarios.
This paper demonstrates that highly crystalline 2-methylbenzimidazole (MBI) films, grown via low-temperature deposition and restrained crystallization, exhibit exceptional fatigue resistance with stable polarization after 10⁸ switching cycles, attributed to localized proton-transfer mechanisms that minimize structural damage during polarization reversal.
This study experimentally investigates spin and orbital torque phenomena in various normal metal/ferromagnet bilayers using spin-torque ferromagnetic resonance, successfully extracting torque components and providing compelling evidence for orbital torque driven by the orbital Hall effect, including the demonstration of an out-of-plane torque attributed to interfacial mechanisms.
