Coherent Spin Waves in Curved Ferromagnetic Nanocaps of a 3D‐Printed Magnonic Crystal

Small, EarlyView.
A nanoprinted 3D magnonic woodpile crystal is measured by microresonator ferromagnetic resonance. Micromagnetic simulations are performed to analyze and visualize the detected coherent spin‐wave modes along the nickel‐coated tubes and caps for various field angles. The woodpile exhibits an unexpected phase evolution and robust edge modes.

Electrical Transport of Nb‐Doped MoS2 Homojunction P–N Diode: Investigating NDR and Avalanche Effect

Small, EarlyView.
Niobium (Nb)‐doped molybdenum disulfide (MoS2) p‐type–n‐type (p–n) homojunction diodes are engineered using thickness‐controlled homo‐interfaces. Current–voltage (I–V) characteristics reveal gate‐tunable rectification, wavelength‐dependent photoresponse, and low‐bias switching.

Engineering Grain Architecture in Epitaxial Aluminum on Miscut Substrates Toward Various Clean Limits and Giant Superconductivity Modulation

Small, EarlyView.
The miscut substrate strategy offers a novel means to engineer aluminum surface roughness, grain architecture, crystallinity, and both normal and superconducting transport properties toward their clean limits by precisely tuning the miscut angle without altering growth conditions.

Intrinsically Chiral Excimers: Water‐Compatible Trityl‐Based Nanoparticles as Tailored Dual Emitters of Circularly Polarized Luminescence in the Vis or NIR Regions

Small, EarlyView.
Dual circularly polarized luminescence (CPL) is demonstrated in pioneering metal‐free organic nanoparticles (ONPs) from a brominated trityl radical derivative. CPL activity in the Vis or NIR regions in aqueous environments is achieved by tayloring the content of radical enantiomers in ONPs, thanks to the generation of intrinsically chiral excimers ...
