This study investigates air-stable, anisotropic CrSBr from monolayer to trilayer, revealing a unique magneto-excitonic duality of Frenkel- and Wannier-Mott-like excitons and demonstrating that while mono- and trilayer systems exhibit similar magnetic responses, the bilayer displays a distinct signature due to different origins of its low-lying excitonic species.
This study demonstrates that pulsed laser deposition, through precise control of growth temperature, pressure, and laser parameters, enables the fabrication of high-quality, highly textured Bi2Te3 thin films on SrTiO3 substrates with tunable stoichiometry and crystalline quality comparable to molecular-beam epitaxy, thereby facilitating the integration of chalcogenides with perovskites for spintronic applications.
This study demonstrates that anisotropic strain in a La0.7Sr0.3MnO3/LaFeO3 superlattice grown on DyScO3 induces selective structural relaxation via domain formation in the LaFeO3 layers, establishing a critical link between strain engineering, structural domains, and antiferromagnetic polydomain states for spintronic applications.
By combining THz-range Raman scattering, single-crystal X-ray diffraction, and first-principles calculations, this study reveals that formamidinium lead bromide possesses a unique coexistence of intrinsic local static disorder and a well-defined average crystal structure, where the former significantly influences the material's structural dynamics and phase transitions across the 10–300 K temperature range.
This paper demonstrates that broken intrinsic symmetry in a synthetic ferrimagnet induces a strong coupling between acoustic and optical magnon modes, resulting in a large avoided level-crossing gap of 3.9 GHz that is tunable via interlayer exchange interaction and exceeds typical coupling strengths in other magnonic hybrid systems.
This paper reveals a novel "hybrid-triggered" ferroelectricity mechanism in HfO where spontaneous polarization arises from trilinear coupling of nonpolar phonons and unconventional higher-order dynamical charges, rather than from conventional structural instabilities.
This perspective proposes the concept of "functional units" as a critical bridge to reconcile traditional structure-property correlations with emerging data-driven AI paradigms, thereby advancing the understanding of material design and knowledge inheritance across diverse systems.
This study experimentally identifies the 3R polytypes of TaS and NbS as Kramers nodal line metals featuring tunable Octdong and Spindle-torus Fermi surfaces, respectively, and proposes a strain-induced phase transition to conventional metals alongside potential size quantization effects in natural inclusions.
This study predicts that Ta3X8 (X=I, Br) ferromagnetic monolayers are spin-polarized triplet excitonic insulators with exceptionally large exciton binding energies, establishing them as promising platforms for spintronic applications and the experimental detection of exciton condensation.

This paper presents a computational framework that combines database analysis with microscopic modeling to predict and identify promising new molecular single-photon emitters, successfully benchmarking the approach on dibenzoterrylene and discovering novel candidates like a chiral emitter.
By utilizing a novel molecular beam epitaxy method to selectively stabilize metastable CrTe and CrTe monolayers, researchers demonstrate that controlling self-intercalation allows for the tunable switching between an antiferromagnetic metallic state and a ferromagnetic semiconducting state, establishing the Cr-Te system as a versatile platform for 2D spintronics.
Using a minimal tight-binding model for the altermagnetic candidate KRuO, this study demonstrates that optically excited spin polarization persists for approximately 1 picosecond—significantly longer than the 10-femtosecond momentum scattering lifetime—thereby distinguishing ultrafast spin dynamics in altermagnets from those in conventional ferromagnets and antiferromagnets.
This study demonstrates that epitaxial growth of monolayer NbSe on graphite naturally forms moir{é} superlattices where interlayer coupling between graphite states and NbSe suppresses charge-density wave enhancement, offering a new pathway for controlling collective states in 2D materials without manual assembly.
By utilizing Coulomb engineering to tune dielectric screening in ultra-clean TiSe heterostructures, the study demonstrates that while the band gap is renormalized, the charge-density-wave transition remains unaffected, thereby ruling out excitonic insulator physics as the primary driver of the phase transition in TiSe.
