Ambient‐Pressure Superconductivity Onset at 10 K and Robust Tc under High Pressure in TiNbTaN3 Medium‐Entropy Nitride

open access: yesAdvanced Science, EarlyView.
The first observation of superconductivity in a bulk MEN TiNbTaN3 with Tc ≈ 10 K at ambient pressure and the electronic specific heat coefficient γ(H) exhibits nonlinear H‐dependence behavior, which is similar to other well‐studied multigap superconductors is reported.

Quantum Thermalization Dynamics of Fermi Gases Quenched to the BEC‐BCS Crossover

open access: yesAdvanced Science, EarlyView.
This study, reporting the first experimental realization of interaction quench far faster than the Fermi timescale in fermionic many‐body systems, explores real‐time quantum thermalization dynamics in the BEC‐BCS crossover. It observes prethermal states with distinct lifetimes after quantum quench, uncovers universal prethermal scaling, and observes ...

Highly Efficient Spin‐Orbit Torque Switching in a Topological Insulator/Chromium Telluride Heterostructure with Opposite Berry Curvature

open access: yesAdvanced Electronic Materials, EarlyView.
This study reports high spin‐torque efficiency (ΔHLJ=12.9×10−6mTA−1cm2$\frac{{{{\Delta}}{H_L}}}{J} = 12.9 \times {10^{ - 6}}{\mathrm{mT}}\;{{\mathrm{A}}^{ - 1}}{\mathrm{c}}{{\mathrm{m}}^2}$) and spin Hall conductivity (σSH=4.8×106ℏ2eΩ−1m−1${\sigma _{SH}} = 4.8 \times {10^6}\frac{\hbar }{{2e}}{{{\Omega}}^{ - 1}}{{\mathrm{m}}^{ - 1}}$), along with ...

Magnetic Precursor to the Structural Phase Transition in V2O3

open access: yesAdvanced Electronic Materials, EarlyView.
V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

Solvated PbI2 Clusters Preceding the Crystallization of Lead Halide Perovskites–a UV/VIS In Situ Study

open access: yesAdvanced Electronic Materials, EarlyView.
This work focuses on the crystallization dynamics in lead iodide perovskite films: In situ UV absorption spectroscopy reveals a PbI2‐DMF solvated (PDS) phase before nucleation, influencing perovskite formation. PDS clusters act as nucleation seeds, linking precursor solution concentration to crystallization.
