Epitaxial strain is a powerful route for engineering ferroelectric phases, yet the role of film orientation remains largely underexplored. Using first-principles-based molecular dynamics, we show that biaxial (110) strain can stabilize a rich variety of nanoscale states, including unusual domains, heterophases, superdomains, and antiferroelectric-like ordering, in the chemically simple perovskites BaTiO, KNbO, and PbTiO. These metastable configurations, persisting across broad strain–temperature ranges, not only point to promising opportunities for large and adaptive functional responses, but also highlight the importance of symmetry breaking by film orientation in ferroelectric materials design.

Topological insulators are known for their highly efficient spin-to-charge conversion, capable of exerting spin-orbit torques in adjacent magnetic multilayers, yet their usefulness in the manipulation of spin textures remains largely unexplored. This work describes the optimization process of a combined topological insulator-magnetic multilayer heterostructure where, through the minimization of the density of characteristic BiSe surface terraces and the insertion of a refractory metal buffer layer, conventional magnetic multilayers with full perpendicular magnetic anisotropy can be grown. Labyrinthine, zero-field domains de-pinned from the TI topography are observed, raising the possibility of future, highly efficient electrical control of hosted spin textures.

Magnetic skyrmions are promising nanoscale information carriers, but creating them efficiently remains a central challenge. Here the authors show that a multilayer’s own dipolar field can be turned from a complication into a design tool. By reversing the Ir/Co/Pt stacking order in half of the film, the layer-resolved Dzyaloshinskii–Moriya interaction is made to work with, rather than against, the dipolar field. This dipolar-field-enhanced effective DMI enables both nanosecond current pulses and femtosecond laser pulses to generate up to twenty times denser, more stable skyrmion populations—without substantially changing the nucleation threshold.

High-entropy alloy superconductors provide a unique platform to explore the interplay between disorder, lattice distortion, and superconductivity. Here, the author investigate the effect of incorporating the magnetic element Cr in a high entropy alloy superconductor (TiVTa)NbCr, revealing a systematic suppression of superconductivity despite nearly constant valence electron count. We show that magnetic impurity scattering drives pair breaking consistent with Abrikosov–Gor’kov theory in this highly disordered system, while strong local lattice distortion coexists with long-range crystalline order.

Linking crack initiation in silicate glasses to shear banding identifies shear localization as a key driver of fracture in this archetypal brittle material. The results unify network glasses with other families of amorphous solids, such as bulk metallic glasses and glassy polymers, by exposing common mechanisms of plastic deformation. This universality calls for a general theory of flow and failure in amorphous solids.

The deformation and flow of complex soft materials are ubiquitous both in nature and across many industrial applications, such as landslides, extrusion flows, and additive manufacturing. This paper reconciles bulk rheological measurements with microscopic dynamics to elucidate complex deformation pathways and fracture events in concentrated suspensions embedded in a hard gel matrix. The results demonstrate that the deformation of such composites is complex, where heterogeneous yielding and fracture coexist and negatively impact shape fidelity in direct ink writing. Rheo-microscopy enables the establishment of a phase diagram to map concentration-dependent deformation regimes and define the boundaries between affine deformation, banding, and fracture.

Altermagnons are collective spin excitations in altermagnets, characterized by anisotropic magnon dispersions. The altermagnet CrSb has emerged as a compelling material owing to its substantial spin-splitting energy. Here, the authors report on the growth of high-quality CrSb single crystals and investigate their thermodynamic and transport properties. A large positive magnetoresistance of nearly 80% is observed at 3.5 K. Interestingly, the room-temperature specific heat exceeds the Dulong-Petit limit, attributed to a broad altermagnon contribution with an energy gap of ~16 ± 1 meV. These findings highlight the potential of CrSb for room-temperature magnonic and spintronic applications.

Antiferromagnetic kagome metals remain far less explored than their ferromagnetic counterparts, despite predictions of unconventional spin textures and emergent transport phenomena. Here, the authors report the growth of single crystals of the metallic kagome antiferromagnet CrRhAs and investigate its magnetic and electronic properties. While no nonlinear Hall effect is observed, Hall measurements reveal an unexpected sign reversal upon changing the current direction, together with a pronounced enhancement below the antiferromagnetic transition. These findings point to a strong coupling between magnetic order and an anisotropic electronic structure, highlighting CrRhAs as a promising platform for exploring transport phenomena in antiferromagnetic kagome metals.

Wurtzite Mn ( = S, Se, Te) is predicted to host multiferroic antiferromagnetic (AFM) phases featuring switchable ferroelectric polarization, with altermagnetism emerging upon Cr doping. First-principles and spin-model calculations reveal a frustrated stripe AFM ground state in pristine compounds, while Cr doping drives a transition to an A-type AFM phase exhibiting -wave altermagnetism with large nonrelativistic spin splitting. Remarkably, polarization reversal switches the spin splitting without rotating the Néel vector. Distinct magnetic phases yield symmetry-selective linear and nonlinear Hall responses, providing clear transport fingerprints and establishing doped MnX as a platform for electrically controlled AFM spintronics.

The kagome lattice has long attracted interest because its geometric frustration can give rise to unusual quantum states. When this lattice is distorted into a twisted or buckled arrangement, the resulting magnetic and electronic behavior becomes even richer. In this work, the authors synthesize and characterize single crystals of ErPdPb, a twisted kagome antiferromagnet in which the Er atoms form a frustrated magnetic network within the noncentrosymmetric ZrNiAl-type structure. Below 2.7 K, ErPdPb enters a strongly anisotropic magnetic state marked by fractional magnetization plateaus, competing exchange interactions, and pronounced directional dependence in its electronic properties. First-principles calculations in the field-polarized ferromagnetic state further reveal a spin-split saddle point close to the Fermi level and a quasi-one-dimensional Fermi surface. Together, these findings identify ErPdPb as a promising platform for investigating the interplay of magnetic frustration, electronic anisotropy, and topological band structure.

Flash events in tetragonal zirconia ceramics trigger unusual mass transport and rapid sintering that cannot be explained by Joule heating alone. To uncover the underlying atomic mechanisms beyond regular machine learning interatomic potentials, the authors developed a machine learning model that also predicts the dynamic response of ions via Born effective charges. These molecular dynamics simulations reveal that an applied electric field significantly enhances the diffusivity of oxygen ions, particularly in the presence of oxygen vacancies. This represents a crucial milestone for understanding defect-mediated ion transport in high-strength ceramics under external electric fields.
