Phonon Scattering by Local Off‐Centering in Diamond‐Like Cu2−XAgxIn2Se4 Chalcopyrites: High Carrier Mobility and Ultralow Thermal Conductivity

Small Structures, Volume 7, Issue 2, February 2026.
Local Ag substitution in diamond‐like Cu2‐xAgxIn2Se4 induces dynamic off‐centering distortions that strongly scatter phonons while preserving high carrier mobility. The resulting interplay between alloy disorder and band structure yields ultralow lattice thermal conductivity and promising thermoelectric performance in this sustainable, tellurium‐free ...

Tuning the Mutual Synchronization of Electrically Coupled Spin‐Torque Oscillators by Selecting the Vortex Dynamic Regime

Advanced Electronic Materials, Volume 11, Issue 9, June 2025.
The synchronization ability of vortex spin‐torque nano‐oscillators is examined across three dynamical regimes: the gyrotropic mode, the dynamic C‐state, and a transition regime. The transition regime exhibits the strongest synchronization ability, and it can be driven into a dynamic state with no ability to synchronize (dynamic C‐state) by slightly ...

Increasing Fire Weather Season Overlap Between North America and Australia Challenges Firefighting Cooperation

Earth's Future, Volume 13, Issue 4, April 2025.
Abstract The USA, Canada and Australia are members of an international partnership that shares firefighting resources, including equipment and personnel. This partnership is effective because fire risk between Australia and North America is historically asynchronous. However, climate change is causing longer fire seasons in both regions, increasing the

In-plane anisotropic optical and mechanical properties of two-dimensional MoO3

npj 2D Materials and Applications, 2021
Molybdenum trioxide (MoO3) in-plane anisotropy has increasingly attracted the attention of the scientific community in the last few years. Many of the observed in-plane anisotropic properties stem from the anisotropic refractive index and elastic ...

Giant tunable topological Hall effect in La0.7Sr0.3MnO3/SrIrO3 bilayers

Communications Materials
The topological Hall effect (THE) arises from a Berry phase imprinted on conduction electron spins as they traverse noncollinear magnetic textures. It constitutes a transport hallmark of chiral magnetism. Very large THE signals are theoretically expected

Induced Ti magnetization at La0.7Sr0.3MnO3 and BaTiO3 interfaces

APL Materials, 2016
In artificial multiferroics hybrids consisting of ferromagnetic La0.7Sr0.3MnO3 (LSMO) and ferroelectric BaTiO3 epitaxial layers, net Ti moments are found from polarized resonant soft x-ray reflectivity and absorption. The Ti dichroic reflectivity follows

Per‐Unit Modeling Standards for Simplified Calculation in Grid‐Forming Converter Systems

Electronics Letters, Volume 61, Issue 1, January/December 2025.
The topology and control scheme of GFMC systems. ABSTRACT This letter proposes a per‐unit modeling standard (PUMS) for simplified calculations in grid‐forming converter (GFMC) systems, which can improve and simplify the modeling process. The proposed PUMS can solve the bottlenecks and difficulties of calculation caused by the upper limits of ...

Ab initio estimation of $E2$ strengths in $^8$Li and its neighbors by normalization to the measured quadrupole moment

, 2022
For electric quadrupole ($E2$) observables, which depend on the large-distance tails of the nuclear wave function, ab initio no-core configuration interaction (NCCI) calculations converge slowly, making meaningful predictions challenging to obtain ...
