Nanoscale Imaging of Strain-Controlled Altermagnetic Domains in {\alpha}-MnTe

This study utilizes scanning nitrogen-vacancy magnetometry to reveal that mechanical strain controls altermagnetic domains in bulk α\alpha-MnTe through a hysteretic process of domain coalescence during compression and metastable fragmentation upon unloading, establishing a pathway for strain-programmable spintronic devices.

Transient Detour and Cooperative Oxygen Exchange in the Polarization Switching of Ferroelectric Hf0.5Zr0.5O2

Using machine learning force field-based molecular dynamics simulations, this study reveals that polarization switching in ferroelectric Hf0.5Zr0.5O2 is driven by a cooperative, transient exchange between 3- and 4-coordinated oxygen atoms involving a unique "detour" pathway and internal self-compensation, rather than by conventional simple displacement models.

Crystal forming ability of amorphous refractory metals under nanoindentation: a molecular dynamics study

This molecular dynamics study reveals that amorphous refractory metals (V, Nb, Mo, Ta, W) undergo shear-driven bulk nucleation and growth to transform into bcc crystals during nanoindentation, with their crystal forming ability decreasing from V to W and scaling inversely with indentation velocity, indicating that the transformation rate is governed by cohesive bond strength rather than thermodynamic driving force.
