Altermagnetic Band Splitting in 10 nm Epitaxial CrSb Thin Films
Advanced Materials, EarlyView.Thin film altermagnets are attractive for potential spintronic applications. How thin can we make an altermagnet before quantum confinement perturbs the distinctive band structure? This paper uses angle‐resolved photoemission spectroscopy to show that the canonical g‐wave altermagnet, NiAs‐type CrSb, grown by molecular beam epitaxy, preserves its ...

Shapeshifting Nanocatalyst for CO2 Conversion
Advanced Materials, EarlyView.A multi‐modal in situ characterization of Ag‐Cu nanoparticles during CO2 photoreduction sheds light on dynamic transformations occurring during reaction. The Cu(core)‐Ag(shell) nanoparticles present the Ag replacement by Cu atoms. Ag is trapped at the subsurface forming a Ag‐Cu‐O phase, and the nanoparticle spreads over the substrate.

Finding the unusual red giant remnants of cataclysmic variable mergers
The Open Journal of AstrophysicsMergers between helium white dwarfs and main-sequence stars are likely common, producing red giant-like remnants making up roughly a few percent of all low-mass ($\lesssim2M_\odot$) red giants.

Tunable Magnetism and Intrinsic Exchange Bias in Al‐Substituted Terbium Iron Garnet
Advanced Materials, EarlyView.Al substitution in terbium iron garnet thin films enables continuous tuning of the magnetic compensation temperature from 190 K to above room temperature. Near compensation, a giant intrinsic exchange bias emerges, whose sign and stochasticity can be controlled by external fields and cooling history. This approach provides new routes to engineer garnet

Advanced Materials, EarlyView.The first room‐temperature, zero‐field observation of stable skyrmion–hopfion spin textures in EuS─Bi2Se3─EuS trilayers is reported. Combining Lorentz TEM imaging and micromagnetic modeling, the authors unveil how interfacial Dzyaloshinskii–Moriya interaction and geometric confinement stabilize these multidimensional topological states.
