Thickness‐Tuned Berry Curvature in vdW Epitaxial Cr3Te4 Ultrathin Films
Advanced Electronic Materials, EarlyView.An investigation of thickness‐modulated Berry curvature in stoichiometric, high‐quality van der Waals epitaxial Cr3Te4 films. Surface and interface Te(CrTe2)‐termination enables Fermi level shifting via thickness variation, modulating Berry curvature near the band crossing point, thereby establishing termination engineering (may called Terminonics) as ...

Advanced Electronic Materials, EarlyView.Localized laser annealing transforms distorted, edge‐pinned domain‐wall motion in ferrimagnetic Pt/GdFe nanowires into straight, stable, and ultrafast propagation. Experiments and micromagnetic simulations reveal an optimum anisotropy‐engineering window in which moderate edge softening suppresses pinning, whereas excessive anisotropy reduction or ...

The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...
