Phys. Rev. Materials 9, 064402 (2025) - Published 3 June, 2025

The study of altermagnets has spurred interest in synthesizing epitaxial films of hexagonal CrSb, a prominent example of this class. However, growing this compound along its high-symmetry $c$ -axis is particularly challenging. Here, the authors report the magnetron co-sputtering-based fabrication and characterization of high-quality single crystalline CrSb(0001) thin film seeded by an isostructural, nonmagnetic PtSb underlayer. PtSb promotes the desired orientation and preserves the intrinsic properties of CrSb, providing a clean platform for studying its magnetic structure, transport properties, and band topology. These results mark a significant step toward unlocking the potential of CrSb in spintronic applications.

Orthogonality point and intersublattice exchange in ${Dy}_{2} {Fe}_{17}$ determined in strong magnetic fields

Phys. Rev. Materials 9, 064404 (2025) - Published 10 June, 2025

The authors investigated the magnetization of single-crystalline Dy₂Fe₁₇ in pulsed magnetic fields up to about 130 T. They observed step-like transitions and identified the orthogonality point of the rare-earth and iron sublattices. Ultrasound-velocity measurements, performed up to 85 T, confirmed one of the transitions. Based on these results, the authors determined the intersublattice exchange field, establishing Dy₂Fe₁₇ as a model system for extreme-field magnetism.

Correlated dynamic disorder, octahedral tilts, and acoustic phonon softening in ${CsSnBr}_{3}$ and ${CsPbBr}_{3}$

Phys. Rev. Materials 9, 065401 (2025) - Published 3 June, 2025

This work reports a systematic comparative study of structural fluctuations and atomic dynamics in CsSnBr $_{3}$ and CsPbBr $_{3}$ . The study combines inelastic neutron scattering on single crystals as a function of temperature with extensive atomistic simulations based on first-principles methods and machine-learned interatomic potentials. The results reveal the existence of two-dimensional nanodomains of correlated tilts of Br octahedra in CsSnBr $_{3}$ , akin to monolayers of the tetragonal phase, similar to those previously reported in CsPbBr $_{3}$ . The correlated disorder results in diffuse rods in reciprocal space, particularly prominent in the cubic phase. The correlations are dynamic with a characteristic lifetime of a few picoseconds, and result from an overdamped phonon branch along the edge of the Brillouin zone. The Sn $^{2 +}$ or Pb $^{2 +}$ ions do not exhibit displacements from the center of the Br octahedron beyond those expected from phonon oscillations.

Epitaxial growth of gold films on the elemental superconductors V(100), Nb(100), and Nb(110)

Phys. Rev. Materials 9, 066201 (2025) - Published 6 June, 2025

Gold films deposited on superconducting materials such as vanadium and niobium can acquire superconducting properties through the proximity effect. Upon annealing, these films grow flat and free of oxygen contamination. Moreover, they can host molecules without suppressing their magnetic states, allowing for a novel approach to explore the interplay between molecular magnetism and superconductivity. This makes them a highly promising and versatile platform for integrating superconductivity and magnetism in future quantum devices, particularly in systems that benefit from strong spin-orbit coupling and molecular-level control.

LETTER

Scaling behavior and giant field enhancement of the thermal conductivity in the honeycomb antiferromagnet ${BaCo}_{2} {({AsO}_{4})}_{2}$

Jiayi Hu, Ruidan Zhong, Peter Czajka, Tong Gao, R. J. Cava, and N. P. Ong

Phys. Rev. Materials 9, L061401 (2025) - Published 10 June, 2025

In this Letter, the authors have completed a detailed investigation of the thermal conductivity of the magnetic insulator BaCo $_{2}$ (AsO $_{4}$ ) $_{2}$ (BCAO) and uncovered two striking features. First, below 10 K, the thermal conductivity exhibits an unusual one-parameter scaling behavior throughout the magnetically disordered regime, corresponding to the range where the zigzag state is suppressed. The authors demonstrate that the intricate behavior of the thermal conductivity in the field-temperature (H-T) plane collapses to a simple scaling function. Secondly, just above the Neel temperature, they observe a giant magnetic-field enhancement of the thermal conductivity, which is closely related to the scaling behavior. From the data, the authors infer that phonons and spins constitute a strongly coupled system in zero field. An in-plane magnetic field steadily weakens this coupling to yield the one-parameter scaling.

Spin polarization of the two-dimensional electron gas at the ${EuO/SrTiO}_{3}$ (001) interface

Phys. Rev. Materials 9, 064401 (2025) - Published 2 June, 2025

Spin-polarized two-dimensional electron gases (2DEGs) are of particular interest for applications in functional oxide electronics. The 2DEG generated by redox reactions on the strontium titanate (SrTiO $_{3}$ (STO)) side of a europium monoxide (EuO)/SrTiO $_{3}$ ~(001) interface is a promising candidate for significant spin polarization. The authors have investigated this 2DEG using magnetic circular dichroism in the angular distribution of photo-emitted electrons and density functional theory calculations with a Hubbard $U$ term. They successfully demonstrated that the EuO/STO~(001) interface is spin-polarized due to its proximity to the strong Heisenberg ferromagnet EuO. Furthermore, they have shown that the spin polarization of the 2DEG depends on the thickness of the EuO thickness when approaching the 2D limit.

Gate-induced carrier control methods are powerful techniques for tuning quantum materials, but their applicability has been confined to thin-film systems. In this study, the authors present the concept of bulk-gating, where the gating technique is applied to a microdevice fabricated from a bulk single crystal of the magnetic Weyl semimetal Co $_{4}$ Sn $_{2}$ S $_{2}$ using focused ion beam techniques. Through ionic gating, the authors achieve substantial electron doping exceeding $5 \times 10^{21}$ cm $^{- 3}$ and a rigid-band-like Fermi level shift, while preserving the magnetic order and structural integrity. This work positions bulk-gating as a versatile platform for exploring carrier-controlled phases and topological phenomena beyond the traditional 2D landscape.

Phys. Rev. Materials 9, 064411 (2025) - Published 24 June, 2025

The performance of any future spintronic device based on thin films or heterostructures may be compromised by thermal effects derived from Joule heating. For example, chemical interdiffusion processes may significantly alter the interface, thus threatening macroscopic behavior. Here thermally driven phenomena are studied in graphene-based magnetic epitaxial graphene/Co/Pt heterostructures. In-situ atomic resolution electron microscopy and spectroscopy are used for direct visualization of thermally activated interdiffusion phenomena at Co/Pt interfaces in the 300 – 773 K range. Noticeable Co/Pt alloying takes place at temperatures above 523K, significantly enhancing the layer coercivity and offering a direct pathway for optimizing epitaxial systems for robust future device integration.

Phys. Rev. Materials 9, 065601 (2025) - Published 17 June, 2025

Coil-helix block copolymers, i.e. blocks with different chemistries and different conformations, are versatile building blocks due to the diverse range of conformational properties that the helical block (pitch, helical radius, persistence length) can adopt. This study uses coarse-grained molecular dynamics simulations to bridge the gap between geometrical and experimental studies of helical polymers by examining the effects of helical conformation on the lamellar phase. In particular, helical blocks with higher molecular aspect ratio and higher stiffness are found to enlarge domain sizes and to produce anisotropic effects such as nematic ordering and enhanced local helicity.
