Stochastic hexagonal injectors in artificial spin ice

Communications Materials
Artificial spin ice (ASI) systems have emerged as powerful platforms for exploring the fundamental aspects of magnetic frustration and topological phenomena in condensed matter physics. In this study, we investigate the bountiful effects that result from

Recent Advances in Ferrite‐Based Materials for Biomedical Applications: A Comprehensive Review

Advanced Materials, EarlyView.
Ferrite nanoplatforms are presented as tunable biomedical materials in which synthesis control, cation engineering, defect/morphology regulation, and surface functionalization govern structure–property–bioactivity relationships. These design strategies enable multifunctional applications including MRI contrast, magnetic hyperthermia, targeted drug ...

Far‐Infrared Hyperbolic Phonon–Polaritons in Zirconium Disulfide

Advanced Materials, EarlyView.
An unpatterned ZrS2${\rm ZrS}_2$ flake, coupled to far‐field infrared light by metal nanoribbons, reveals hyperbolic phonon polaritons with multiple higher‐order branches and effective refractive indices up to 223. This resonator‐assisted approach establishes ZrS2${\rm ZrS}_2$ as a compact van der Waals platform for deeply subwavelength far‐infrared ...

CVD Grown Hybrid MoSe2–WSe2 Lateral/Vertical Heterostructures With Strong Interlayer Exciton Emission

Advanced Materials, EarlyView.
A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Unveiling α‐MoO3 as a High‐Index, Low‐Loss Anisotropic Material: Bridging the Gap From Mid‐Infrared to Ultraviolet Nanophotonics

Advanced Materials, EarlyView.
α‐MoO3 is established as a high‐index, low‐loss anisotropic platform bridging mid‐infrared polaritonics and ultraviolet‐visible nanophotonics. Spectroscopic ellipsometry and calculations reveal refractive indices exceeding 3.9, with the largest in‐plane birefringence among transparent layered crystals at 425–500 nm, enabling zero‐order UV waveplates ...

Photoactive Tweezers

Advanced Materials, EarlyView.
A photoactive tweezers system based on photoactive colloids is developed and systematically investigated in this study. Through experimental and theoretical methods, we demonstrate that the photoredox reaction catalyzed by a dye‐sensitized TiO2 particle generates a strong positive phototaxis, enabling self‐entrapment in the beam center.

Chiral Altermagnetic Magnetoelectrics

Advanced Materials, EarlyView.
In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements

Advanced Materials, EarlyView.
Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.

Direct Growth of 2D Bilayers on Au(111) for Low‐Coercive Sliding Ferroelectricity

Advanced Materials, EarlyView.
Controlled CVD growth of stacking‐defined bilayer ReS2 on Au(111) enables parallel‐stacked bilayers with intrinsic sliding ferroelectricity, a strong piezoelectric response, and an ultralow coercive voltage. Atomic‐resolution imaging and in situ measurements further reveal the decisive role of clean interfaces in achieving low‐barrier ferroelectric ...
